My favorite Canabalt clone, Scott "Spiritonin" Stoddard's Robot Unicorn Attack, originally released online for free as a Flash game by Adult Swim, will make a magical jump to iPhone/iPod Touch on June 1st with a $2.99 price tag. To celebrate, I've created an iPhone wallpaper version of Quix Maiquez's tribute art for the game, pasted after the break.

If you've not played Robot Unicorn Attack, it's an addictive two-button game in which you command a magnificent, rainbow-maned mechanical beast as it leaps across chasms, collects fairies, and dash through stars whilst Erasure's amazing song "Always" plays. Yes, the game is as life-changing as I make it out to be.
