Shrapnel Games has announced the availability of Brainpipe for the Macintosh. This single-player arcade-style game reportedly allows you to “relive the 60′s and 70′s without getting hassled by The Man”. It offers 10 levels of “ramping perlexity and oddness” with “eight distracting obstacles to avoid”. It’s described as “a plunge into unhumanity”. It requires Mac OS X 10.2 or later, a 700 MHz G3 processor, 128 MB of RAM, 40MB HDD, and a 32MB 3D video card.

There is also a Windows version, which requires a Pentium 1.8 GHz, 512MB of RAM, Windows XP or Vista, 50MB HDD, ATI Radeon 700+ or NVidia 6800+ video card, a Windows compatible sound card, and OpenGL 1.1 compatible drivers.
