The main article of the 45th issue of Hacker Monthly
magazine was Bitcoin,
and Cheng Soon asked me to do an illustration for the cover. It was refreshing to work again for Hacker Monthly... literally! With my wife and daughter we went out for ice cream and sodas while I drew four ideas for the cover. Cheng Soon gave the thumbs up to the first sketch.
The coin was drawn using Paint Tool SAI's vector layers, since Photoshop Elements 2.0 — the reduced version of Photoshop that I own — lacks vectors. All background layers were done with PSE20.
The source code that appears on the upper left is Bitcoin's, src/coins.cpp
to be precise.
Oliver asked me if the ones and zeroes at the bottom right had some secret message, but no, they were typed in at random.
