The Spintronics video mentions the simulation of resistors, capacitors, batteries...but not logic gates. It doesn't seem to teach the magic of boolean logic at all, which is a bit disappointing. (but not as disappointing as the Fisher Price music player!)

For that, you want turing tumble (which was released first, by the same team).

There are transistors. You can string a few of those together and get any logic gate you want...
