A few weeks ago, Belgian casemodder Piloux turned some heads when he presented his HL2-themed mod "Blackmesa HL²". He seems to also have caught some attention over in Bellevue, WA, as Valve now asked him to create another casemod for their main conference room. Citing Piloux's post on the bit-tech forums:

After the big success of my Blackmesa HL2 case I received e-mail from Gabe Newell, and he asked me if I can build a similar case to use in their main conference room to show game's demo... well, that was an offer I cannot refuse.

I am somewhat certain noone would have refused that offer, so head on over to the bit-tech forums and check out the progress on this Valve-funded masterpiece.
