Heads just blown up. How's this for a throwback? I'm sure we all had one back in the day? If you didn't, it's £1.07 delivered, you won't know caring for something, until you care for your virtual pet.
There were other options available around the same time, I'm sure the Sega Dreamcast had one for the VM unit? (Sonic Adventure, maybe?)
Buy one, slap it on your keys and tend to it. Best £1.07 spent today.
