Intro

<p>The psychedelia of the 1960s and 1970s is back in a big way in electronic form at Apple's iTunes store. Many dozens of apps let users trance out to hallucinogenic displays ranging from virtual lava lamps and kaleidoscopes to touch-screen-generated whorls of color. <br><br>For those looking to "turn on, tune in and drop out," here are 12 trippy apps.</p> <p></p> <p></p>

<strong>Trancit</strong>

<p></p> <p></p> <p>"<a href="http://itunes.apple.com/app/trancit/id292879633?mt=8">Trancit</a> is a dynamic visual experience that will draw you in, relax you, and stimulate your mind," writes Ken Karakotsios, the maker of this app on its description page. (Karakotsios also created the early 1990s computer game SimLife.) Users can shake, tilt and swipe on their devices' screen in various directions to make the Trancit images do funky things. Swiping down selects one of the eight color palettes and swiping to the right brings up one of 11 different visualizations that have names such as Tie Dye, Crystal Math, Diamond, and Hot Frost. Shaking makes the pixels move randomly, or "carbonate" for a few seconds. Swiping to the upper right "zaps" away most of the present image's pixels so it can start evolving all over again.</p> <p>$.99</p> <p></p>

<strong>iLava</strong>

<p></p> <p></p> <p>Gotham Wave Games, the designers of <a href="http://itunes.apple.com/us/app/ilava-virtual-lava-lamp/id298849096?mt=8">iLava</a>, invite customers to "turn up the music and chill out with this groovy, state-of-the-art, interactive lava lamp simulation." This pocket-sized version of the popular dorm room accessory realistically simulates fluid dynamical motion. Users can even "heat" the flowing, glowing blobs with their fingers by touching the screen so they move faster. Crucially, as with other trippy apps, background music from iTunes can play while the six different colors of virtual magma bounce, blend and wobble all over the display.</p> <p>$.99</p> <p></p>

<strong>iPsychedelic</strong>

<p></p> <p></p> <p>Developer Ubik aims to blow your mind with its <a href="http://itunes.apple.com/us/app/ipsychedelic/id327720703?mt=8">iPsychedelic</a> app. "Control a liquidy flow of spectacular plasmatic stars with your fingers!" the description says. Touching the screen makes sparks fly and swiping around manipulates these starlike particles and the fluid medium that suspends them. Color options and some built-tunes round out the out-there experience.</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">Volt </span></strong>

<p></p> <p></p> <p>Before one trances off into a full swoon, charge up with the eye-popping <a href="http://itunes.apple.com/us/app/volt-3d-lightning-unleashed/id349953604?mt=8">Volt app</a> by Jack Everitt. This application lets users unleash colored 3-D lightning from their fingertips. The bolts' hue, power, energy, number and more can be tweaked, and zapping electricity-esque sound effects come standard. Star Wars fans looking to get their Sith on can load a photo of a Jedi adversary and perform an Emperor Palpatine-style electrocution of their face with lightning bolts.</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">Kaleidic Lite</span></strong>

<p></p> <p></p> <p><strong></strong></p> <p>CapeApps' <a href="http://itunes.apple.com/us/app/kaleidic-lite/id305557129?mt=8">Kaleidic Light</a> digitally reinvents the kaleidoscope on your iPhone, iPad or iPod Touch. Sixteen different mirror configurations plus a range of gestures from shaking to tilting generate an endless array of multicolored crystalline images. Pictures from a personal photo library can also be brought into the kaleidoscopic mix and broken apart into gemlike pieces.</p> <p><strong></strong></p> <p>Free</p> <p></p>

<strong><span style="text-decoration: underline;">Hypnotical</span></strong>

<p></p> <p></p> <p>This app showcases 11 hypnotic images plus a "techno soundtrack to keep your patient" – or yourself –"in a constant state of hypnosis," goes the iTunes store description from designer Inner Four, Inc. Note that the dizzying visuals are not guaranteed to induce a genuine state of cognition where ridiculous suggestions pass muster, and that's probably a good thing. The makers also suggest some other uses for <a href="http://itunes.apple.com/us/app/id334249357?mt=8">Hypnotical</a> — as a flashlight, for example — or "even a techno glow light at your favorite club or rave!"</p> <p>Free</p> <p></p>

<strong><span style="text-decoration: underline;">Gloop</span></strong>

<p></p> <p></p> <p>As detailed by maker RunSwimFly, <a href="http://itunes.apple.com/us/app/gloop/id325378980?mt=8">Gloop</a> "sits somewhere in that improbable space between an interactive lava lamp, foam resting on water and alien clouds lit by the setting sun(s). Whatever it is, as you stir this bizarre mix thousands of virtual molecules collide with each other, sticking and slipping. This generates heat causing the gloop to glow and become less viscous. If you treat the gloop more gently it cools and solidifies allowing you to give it form." If that's not trippy, we’re not sure what is.</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">Visual Goodies</span></strong>

<p></p> <p></p> <p>This <a href="http://itunes.apple.com/us/app/visual-goodies/id323455351?mt=8">interactive particle app</a> includes fire, smoke, flower effects and more, according to developer SMART WIRE LLC. Finger-tapping the screen spices up the animations as well.</p> <p>Free</p> <p></p>

<strong><span style="text-decoration: underline;">TrippingFest 2</span></strong>

<p></p> <p></p> <p>The spirit of Jerry Garcia lives on in this drawing and sketching application by ForestHeller.com. The iTunes description lists specialties including optical illusions, symmetry-based drawing, flexible coloring and, of course, "craziness." Overall, <a href="http://itunes.apple.com/us/app/trippingfest-2-drawing-sketching/id320191238?mt=8">TrippingFest 2</a> invites users to "draw like you have never drawn before" and "draw lots of incredible drawings very quickly."</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">Pulsar</span></strong>

<p></p> <p></p> <p>"Control a virtual supernova of particles that can be tweaked into near-infinite combinations," says RGB.nu, maker of the <a href="http://itunes.apple.com/us/app/pulsar-interactive-particle/id293703712?mt=8">Pulsar app</a>. The right side of the above screen image shows that a number of options (17 in all) can be adjusted to cook up a mind-melting visual. "There is no particular goal or result to achieve, other than the enjoyment of tweaking parameters to make something that looks cool," the Pulsar description reads. As for inspiration, that's up to you.</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">iBurn 3</span></strong>

<p></p> <p><br>A must for those who have a soft spot for psychedelia with elements of pyromania, <a href="http://itunes.apple.com/us/app/iburn-3-draw-with-fire/id304923687?mt=8">iBurn 3</a> is all about playing with digital fire. The flames in this simulator come in a dozen hues and they follow the orientation of the Apple device as a real blaze might. Designer iNiark says you can "simulate a lighter" or "take a photograph and make it look like it is lighted by a campfire or as if items were burning." Assuming the latter doesn't freak you out too much, remember to either blow into the microphone, or, eschewing common fire safety sense, touch four fingers to the screen to extinguish the fire.</p> <p>$.99</p> <p></p>

<strong><span style="text-decoration: underline;">Galactica</span></strong>

<p></p> <p></p> <p>With this <a href="http://itunes.apple.com/us/app/galactica/id310867190?mt=8">cosmically inspired app</a>, users "emit streams of plasma" from their fingertips, "ignite explosions of dust and gas," and use gravitational-like forces to mold their own private sparkling universe, according to the description by maker Thumbspark Limited. The app comes loaded with three original musical tracks or iPhone, iPod Touch or iPad owners can select their own funkadelic tunes to accompany the graphics.</p> <p>$.99</p>
