Here's the final version. The original file was printed out into 2 13x18 posters. One of which I gave to Fred (the artist and writer of Megatokyo), and the other I'm keeping for my portfolio.
The original image checked in at 150 mb. So I obviously shrank it down for posting here. It's 17% of its original size.
No more posters will be made, in respect for Megatokyo.
