Today we cut out 4 yellow triangle pieces. Each piece is 100 mm on a side and feature seven 5 mm holes. The tips of the triangle and rounded so not to be too sharp. The holes on the sides are centered 5 mm from the edge, so there is 2.5 mm between the edge of the triangle and the edge of the hole. Each piece has a triangle pattern etched into the center. We painted one of the triangle with black paint to highlight the etching.

The 5 mm holes work great as Acroyear is demonstrating.
Here is a close up of the unpainted etching.
And the painted triangle.
In the following picture we used red electrical tape to simulate the red connectors from the prototype pictures to make a pyramid shape.
It already fun to play with and we only have one of the shapes!
