This was a toy designed in the 1960's by the same company that made the Digi-Comp (of which more later).

The K'nex Think-a-Dot

I had had this in the back of my mind ever since I saw the Knex-i-Comp, but only realized how it could be done after building a Big Ball Factory. This included the flip-flop ball router that is central to the Think-a-Dot.

Here are some pictures:

• Introduction
• Mounting Clip
• Front View Without Screen
• Flip-Flop
• Flip-Flop Movies
• Bottom Row of Flip-Flops
• Bottom Row
• Template for Cutting the Front Screen

There are only a couple of things that I don't like. First of all, I should replace the cardboard screen with a nicer white one, and replace the blue and pink dots with stronger-colored blue and yellow ones. This would be more like the prototype. Second, I want to add some support to make the base slightly wider, as it is a bit unstable at the moment.
