Here are balancing/stacking toys I made for a grandson and granddaughter for Christmas. If you have been watching the projects posted on Lumberjocks lately, you will recognize this toy from a post by jbschutz. My thanks to jbschutz for kindly sharing his pattern for the balancing guys. I made the balancing guys and painted them. I think look like Meeples from the board game, Carcassone, and that is the name that stuck for them at our house. I made a pair of boxes to keep the “Meeples” in with box joints. When the Meeples are stacked in their boxes, I think they look like the ancient Chinese Terracotta Warriors. Merry Christmas to everyone!!!

Magic Tables Optical Illusion

Here’s an illusion we already had an opportunity to experience first hand in one of our earlier posts. This is the best example I’ve seen up to date. Although it may seem intuitively impossible at first, when we take the shape of the table surface on the left and apply it to the table on the right, it matches exactly! If you don’t believe it, measure the tables with a ruler. Same goes for the books on the tables (they’re both the same size). Amazing isn’t it? Check out the animated proof I created for you below:
Although the brain is aware that these are flat pictures, it constructs a perception of the tables in which depth is taken into account. In this process, the brain unconsciously interprets that the actual depth of the table surface projected onto our retinas should appear shorter than they actually are, and compensates to make them appear longer.
Even after we discover that the two table surfaces are same in size, we still can’t change the interpretation that the brain has constructed! Check the animated proof below, and try to pinpoint at which frame does your brain start to perceive the table surfaces as identical.

On youtube I found videos from marbles the brainstorm introducing this game. Since they don’t ship to foreign countries I decided to build it myself and if turned out to be a fun project that was fairly easy.
The benefits of color sudoku compared to the regular sudoku are great. Everybody around the table can participate, kids can play it, it decorative …
I just posted a video on youtube on how I built it. So check it out and make your own game if you like it.
