I can’t seem to stop playing with Logicly! It allows you to make circuits in flash and then watch them run. I made a clockless circuit, but the more industrious out there may want to try making something with a little more power.
Try and make a circuit that adds in a gray code! Or in binary! Watch it count up using the clock! For some reason, this is just totally fun. Now I want to have one that uses Hadamard gates so that all circuits will be reversible…

7 (111 in binary) plus 0 (000 in binary) is 7

7 (111 in binary) plus 1 (001 in binary) is 8 (1000). Check out all that ripple-carrying!
