Windows users should have relatively simple control through an app if they just want to play, but where Fritz may shine is its open source nature: the code and hardware schematics will be available for extending support, changing the look or building a larger robot where Fritz is just one part.
As such, Puzzlebox will also freely distribute all material in relation to the project, from the source code to the hardware schematics to how-to guides for dismantling and reassembling the whole thing.
