So I guess this is older news, maybe it's been discussed before, but a video of out in action appeared on my Twitter feed this morning, and it just screamed grm.
Some arduino and software work, and your gold fish can chase the cat all around the house.
I can't share the video from Twitter, but if you have it, check @inthenow_tweet feed for a link, the video is pretty cool.
YouTube video sorry, I can't embed video from my phone
