Recently, he had to say goodbye to his old lab and move into a much smaller, more sterile looking one. He seemed pretty depressed about it, and when asked if he'd be putting up any posters or comics he replied that that wasn't likely. So I made him this to hang on his door for Hannukah.
The banner is made from multiple thin strips of paper running horizontally, with vertical lines of string running between them every 3/4 of an inch or so. Very hard to draw on, so there's limited room for detail. It's a chinese wall calender I got at a buffet in Cincinnati years ago. 12x36 inches, with microbes, cells, and histoplasma leaping epically out of a petri dish. He loved it :)
Happy New Year!
