Autism: I drew this when I was supposed to be working.
True story. Actually, the only job I managed to get was as a cleaner at the college in the town where I live. It was suited for me, because I could go in early and do my job and leave before the Students even arrived.
I screwed that up though, the anxiety got me and I lost the job because I couldn't cope with a sudden change in their routine. That's just my life in a nutshell.
Anyway I'm Autistic and I love GPUs, so obviously I had to draw an architectural, top-level block diagram for the GM204 GPU, at work on a piece of paper entirely from memory. >_>
