Shape of things (to come)

Time for catching up with the 3D design. Handy when my own programming brain also is temporary overloaded. I decide to produce my own objects for the memory game, either casting them (plaster or concrete) or shaping them in the actual material (the best would be stone - but guess I’m landing on wood or cibatool). The idea with the objects is to have no visual clues, not even tactile symbols in this trial version of the concept that I’ve decided to go for. The only detection should be the reaction sounds from the dog. The shapes should be small enough to be enclosed in the kid’s hand, a possible secret treasure. Inspired by the natural irregularity of beach stones, I model out some suggestions in wax.

The cubic shapes is supposed to be softly geometrical with different radius and slightly concave/convex surfaces. The more naturalistic stone shapes is even softer. Since the arphids I wanna insert are flat, inexpensive 20 mm chips, the shapes must be a bit flat to not becoming too big. A wish from the blind center is that they also should be flat enough on at least one side to not roll away on the floor like an ordinary marble.
To make them desirable for blind kids (as well as seeing) I wanna focus on the quality when touching them, both in surface materiality and in shape. Their sublime irregularity should give them a tactile exciting quality, as well as being interresting to collect and also to feel under the fabric covering the dog’s stomach. I’m imagining the objects being produced in enough hard material to have a clinking sound when they touch each other. The best would be if they also had some natural weight (I’m now skipping the idea of a built-in weight in led because that would cause interference with the arphid detection), and since they are so small the material should be as massive as possible. I have to test out how much that weakens the detection though.
