My wife just found this, came out today: Coaster iSim [Alternate AppShopper link] It's a total rip of Air Coaster 3D, but with a contrived name and lame use of the "i" meme, and minus the panoramic backdrops, music, etc. It also features a 3D mode, but it uses the cross-eyed stereographic method used in MagicEye images. (Yay! Migraines for everyone! Except Silent Bob.) Looks like a cheap attempt to cash in on Ziconic's success.
