- 26th July 2008: Mr. Do - Funny story. Tormod sent me a BUNCH of instruction cards a long time ago. You've probably been seeing them added in every so often. Well, around July of last year, I had completed a whole bunch of them, but then had a computer crash, and they ended up on the "spare" hard drive by mistake. I found them again going through a cleanup. So thanks to Tormod, this week we have Viper Phase 1.
