(There's no video for Core! yet. Please contribute to MR and add a video now!)
Core! is a B&W "Redcode" development system for the Macintosh. Basically, you can program robots using assembly-like language called "redcode" to fight against each other in boolean grid environment. Core! can simulate step by step or automatically and record the whole tournament events to a single text file with date/time stamps so that you can leave the application running the simulation for a while and then come back to read the results in the output file. You can also watch it go, since the grid is updated in real time, graphically representing the battle.
