As a fan of the Amiga from way back in the day I have to say that some of the most inspirational artwork I ever saw was Dan's work.

Speedball 2 was awesome and obviously his work on The Chaos Engine was simply amazing. As a young artist dabbling in DPaint I never tired of staring at dans work. I also managed to see some of his pre production sketches once, and again, it was so inspiring to me. There are times when I still feel like that now, but they are few and far between, maybe it's just my age :P
