It’s off topic, but I heard about a maze competition that might interest some people here. Competitors program mouse robots to navigate a maze in the shortest amount of time.

I <3 Floodfill.
Floodfill 4 life.
Personally feel floodfill is a technique for life.
Choose the shortest path, run into a barrier, adjust to the newest shortest path.
Ps. oddly enough my friend sent me this video last week, and I have since shared it a few times. Then it pops up here… very cool.

It looks like a lot of fun. If I had more free time I’d probably look into it more. 
I found a page that lists some competitions:
