Query: Good new idea for a toy, both educational and clever

I think this is both a clever idea, a new strategic game, and educational. Like chess it forces people to think about their move and their opponent's move and to think ahead. It's easy to get started, and the different setups make it easier not to have the game repetitive. If one person already has a sense of angles and the other doesn't, however, it's going to end quite quickly. The add-ons (beam diverter kit anyway) make the game a ton more complex and maybe are required to make the game more challenging for folks that are fairly good with simple angles who are already familiar with other strategic games.That kit may make it too complex for kids that are new to it but it can be used selectively and is not expensive.
