This doesn’t exactly fit in the category with all my digital products but back in University I developed a Marbletrail builder with Virtools to learn more about building, saving and loading levels. Few years later I paid a friend of mine as an industrial designer to make real life prototypes to be compatible to Lego Duplo toy bricks. That step was successful but I didn’t had much time to take care of pushing this project further because I was knee deep in work with my startup Monkeyhead Studio. So I agreed that he would continue development and engage possible partner companies for production. To make a long story short those marble trail bricks are now produced and sold by the company Hubelino. It’s nice to know that I invented those things even that to this day I don’t earn any money from them.
