This is a great idea. Huge posters can be made cheap and easy by printing out rasterized images. E.g., a 66″ x 51″ poster is printed from 36 sheets of 8.5″x11″ paper.
As an example, check out this 36-page FSM Mural posted in the dorm living room window panes facing the activities hall at Pitt Greensburg.

(Thanks to Brendon for doing this.)
You can make your own giant rasterized images using the Rasterbator.
Or, here you’ll find a few ready-made rastorized images. They’re in .pdf format. Click to download:

Pages: 6 x 6 = 36
Dimensions: 1.67M x 1.26M

Pages: 5 x 4 = 20
Dimensions: 1.08M x 0.95M

Pages: 8 x 4 = 32
Dimensions: 1.73M x 1.08M
Print them out, assemble with copious amounts of scotch tape (or possibly duct-tape depending on your mood), and post the thing where everyone will see it. Send me pictures/videos if it’s particularly impressive.
