This (it will move here in a few days) was a pretty fun puzzle. The first 11 puzzles were really simple and only took me a few seconds each. The last puzzle took a few minutes. I could have written a program to solve it like I have on previous puzzles, but I thought I'd figure it out the old fashioned way. I got about 30% of the way through the puzzle using basic logic. Then, I took a screen capture and started making some guesses. If I had to backtrack, I had my screen print to work with.
Here's the answer:
I haven't been posting much on my blog lately. I'm losing interest in the Google puzzles, and the quality of these puzzle isn't very consistent.
I've been trying to read up on 3d graphics and quaternions so I can do some puzzle programming for my PDA/phone. I'm probably going to to stick with PalmOS API's, although I'm considering J2ME.
