Red, I know what you mean, my kids would always catch him on the ground. I guess the timer does the autofocus part superfast, that is hard to do with our finger. Try it out, I set mine to take the max pics (10), and did it 3 times, so out of 30 pics, these were the ones that made the "cut", lmao.
Thanks E, and yup, I made it from the D.I.Y thread on GP. I think I used a 7' piece. Let me know if you want me to take some close up shots of it to give you a better look.
