Triskit is a fascinating project that takes the form of a self-generating toy system. If you own (or have access to) a mini laser cutter or acrylic sheet stock then you can use the Triskit software to design pieces for your very own toy system (called a Triskit). You can use the data that is produced by the software as input data for your laser cutter and the result is your very own, custom-made toy part.
One of the benefits of this is that, if you are trying to build a toy and find that you don’t have a particular part that does what you need, you can just make one to suit your needs. With the likes of LEGO and K’nex, you are limited to what pieces came in the original box.
