A "recommendation engine" tool from Madonion.com for Windows.
XL-R8R ("Accelerator" in the language of tr00ly r8d g8mRz) is a system comparision program. Basically, it makes a list of the widgets attached to your computer, and compares the list with others over the net. It's something sort of like a 3DMark, but doesn't really do a benchmark, just a list of hardware.
It has a pretty nice demo-like thing (just like most of the other Madonion's products) that obviously drew most of its influences from Star Wars and The Abyss (and also has a room from 3DMark 2000)... not bad, and the absolutely rulesome soundtrack is also available as an MP3 from the website.
