Some number of months ago (more than half a year, I think) I discovered a program called The Rasterbator. It takes an image and turns it into “dots” like newspaper pictures, but at a much larger size. This lets you grossly enlarge an image without the “jaggies” or “fuzzies” that happen when you make it too big.
I used it, because it was neat and it’s fun to try out neat things. I finally settled on a Skaarj picture that looked rather cool. But there were two problems after I used it.
1) I didn’t have a paper cutter to put all the pieces together.
2) The printer ran out of black ink halfway through the printing.
The second item went unnoticed until just recently when I was putting it together.
In any case, the printout was 7×5 pages, and made for a very large poster. Here it is, with a reference shot of me (cut off about at the knees) in the lower right corner. The image has been edited to remove clutter and a doorframe.
