I was thinking about what to do with Light Logic and the answer is fairly broad. I have had some comments from folks being sad that I have ended my work on IO the Cardboard Computer. I had already decided to design and build a better version and its name will be IO2. It's a long shot but IO2 will now use only Light Logic gates so IO2 will be a CPU / MCU without any transistors, relays or valves. That will be a very interesting light show indeed as each gate will light up when active.

I am also interested in building a sound / music synth and would like to incorporate Light Logic into it as well.

Bottom line, any circuit that requires a logic gate can use Light Logic.
