Fisheye Lens on the Cheap

I love stuff; but I hate paying full price for it.
(e.g. I love Rubio’s fish tacos, but I’ll only buy them on Tuesdays when they’re $1.00/All of my designer clothes are made by Cléarãnce and Salé/When ppl have free dirt in their driveways after having a pool dug, I’ll pull over and take a couple of pocketfuls.)

But the point that I’m trying to make is; nice things usually cost a lot of money, and I don’t like that.  For me to get a fisheye lens for my Canon Point-and-Shoot would require more than I’d like to spend so I decided to make my own.
