Late last month, Linux enthusiast site Phoronix found definite proof that Steam is making its way to Linux soon in the form of Linux binaries hidden within the recently released Mac OSX launcher beta. These binaries in their pure extracted form unfortunately did not run successfully.
However, a number of independent users have been hard at work, and now the first fruits of their labors have manifested. Phoronix reader Kame has released a pair of screenshots showing the Steam client compiled and running natively on a Linux platform.
The screenshots only display a basic initial login screen and it still is not fully functional. However, it does show that the framework is indeed there, and Valve is hard at work to make good on their two-year old promise of bringing their game platform to Linux.
