This is a cover for Phlogiston's "Game music 1" album. You can get it here: http://www.iimusic.net/plus/2009/10/game-music-1

The image is basically a re-imagining of the visuals of the game "I was in the war" by Bisse: http://www.indiegames.com/blog/2008/07/freeware_game_pick_i_was_in_th.html

You can view a video of the drawing process here: http://www.youtube.com/watch?v=ZSL-soJi8kM

(At one point I thought I had lost the recorded footage, so I didnt bother to record the final part of the drawing! It sort of cuts short, its missing maybe 30-40 seconds of video (which is about 1 hour of work maybe?)
