Fine Structure

Our favorite imaginary scientist, Dr. Gordon Freeman, is quietly celebrating ten years of science mishaps and interdimensional alien invasions. Valve is celebrating as well by practically giving the original Half-Life away at a mere 98 cents. If you don't own it (rare, but possible!), it's a good day to pick it up!
