A simple interface for children to use a PC. Brightly coloured cubes about the size of an orange were to be hand held and on rotation the orientation of the cube would be sensed and processed by a PIC processor and radio-transmitted back to a pc to act as a mouse input. The surfaces were coloured differently and the system would know which colour was on top at any time.
Above is all I have of the cubes project - the very first test model and my first Visual Basic cubes monitor program.
