I love the Rasterbator, but I also love the crispness of vector graphics sometimes. Why not create a large Rasterbation-like poster with exact lines and shapes? It's actually really easy.
I used this technique to create a big poster for a Daft Punk dance party my friends and I were throwing. I was really happy with the output, and the night before the event someone even stole the poster. That's a compliment in my book!
Sorry for the quality of the photo of the final product -- We finished at 2AM and were really tired.
You'll Need:
-An image (most any format, but if it's already a vector (PDF, EPS, SVG, etc.) you can skip some steps).
-Laser printer: Preferably one where you don't have to pay per page. Depending on your image, you will use a lot of toner, so keep that in mind.
-Paper cutter (scissors will work, but will take much longer)
-Scotch Tape
-Markers, Colored Pencils, Crayons, etc. (optional): Adding color accents can really have some outstanding effects.
-Software: Here we have some choices:
-Adobe Suite: This is expensive software but the way to go if you can. I had access through my school, so check on that if you are associated with an institution. I used Photoshop, Illustrator, and Acrobat.
-Open Source Software: You can definitely accomplish this Instructable using only open-source software. Try GIMP for raster manipulations and Inkscape for vector tracing, manipulations, and tile printing.
-Web-Based: if for some reason you don't want to download a bunch of new software, you should be able to use web services exclusively. The only downside is that (as far as I know) there aren't too many web based resources for editing vector graphics. You could use Photoshop.com (requires creation of a free AdobeID) for raster work, and Vector Magic (or Potrace) to do a vector trace of raster images. I haven't done this, so let me know if you find a good workflow.

Signing UpStep 1Working with your raster image
In order to prepare the raster image for a vector trace, it helps to create a simple black and white image (no grayscale) without losing important parts of the image. The easiest way to do this is:
-Eliminate any unwanted parts of the image,
-Increase contrast to maximum,
-Adjust the brightness to keep desired details,
-Manually retouch tricky spots.
Depending on the image, this can be straightforward or require a bunch of work. So pick your image carefully. My image (found via Google Image Search) already incorporated some crisp lines, so this step was relatively easy. I got rid of the color and took out all the type. The reflections on DP's helmets were my only challenge, and required going back over those parts of the image with a black paintbrush. You really shouldn't feel restricted to vector-like images, though. You can get some great results from plain old photographs. Check out the vector trace I did of this old biking photo (also from Google).

Also: Since photoshop can't livetrace, enlarge the image (I made mine 34x22in, it was originally 26x16in) and add a filter. My favorites are halftone pattern, angled strokes, chalk and charcoal, note paper, and patchwork. if you're starting out from a really small image, enlarge it, then add the cutout filter and some others.
