Magic Tables Optical Illusion



via Mighty Optical Illusions http://www.moillusions.com/2012/12/magic-tables-optical-illusion.html

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:


Magic Tables Optical Illusion



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.

Color Sudoku Game


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.

Dice Puzzle Box


Here is a box I made for this dice puzzle . I got the idea for the design from something Gene (vipond33) said in his comment for the puzzle. He said all I needed now was a box with the same design as the dice pips and I was done! Well, thanks Gene for the idea!


The box is mahogany with a scrolled lid. The scroll work is a little rough, but I’m just learning! The backing for the lid is maple. This also creates the lip for the lid. The joints are mitred. I routed a 45deg v detail. Finish is two coats of quick dry gloss varnish.


This box makes me feel a lot better about giving this puzzle as a gift now.


Thanks for looking, and, as always, comments welcome
