So I had this huge bare patch on the wall.
Problem is: it's such a sappy, feel-good market for teacher posters. Anyone else feel me on that?
I mean, if you're looking for something totally insulting — Mary Lou Retton smiling broadly next to the quadratic formula captioned with "MATH IS A PERFECT TEN" — you're in luck. Otherwise, you're out of it.
That was me. I wanted something risky. Something out there on the edge. You want that, I figured, you've gotta do it yourself.
Then I loaded it into Rasterbator. Here's hoping your district hasn't installed a rhyming module for its filtering software.
You decide how many pages tall and wide you want the final product1 (I chose 5×5 but it can get huge) and then let 'er go. It spat out 25 pages of rasterized goodness.
The result is everything a teacher poster oughtta be. Edgy, unpredictable, dangerous. I only regret not taking this even larger.
I realize everyone's gonna want one so here's the original.
Update: Eric adds:
If your district does block the rastorbator, http://www.blockposters.com does basically the same thing. And you can tell your students the name of the site without feeling dirty.
