He lives on a server. Olti's brain runs on Cloudflare and wakes up every minute, day and night, whether or not anyone's watching. This page just looks in on him.
Needs. He has five: food, energy, fun, company and curiosity. Each one drains a little every minute, and he decides where to go to top them up.
His own ideas. Every few hours, if he's content, he dreams up something new to build, designs it himself, and builds it near a place he loves. Nobody tells him what to make.
Finding things. Out and about, he sometimes finds things. He decides whether to keep them, give them to the museum, put them on display, or leave them be.
Your gifts and notes. He reads everything you leave him and writes back. He decides what to do with gifts himself. If he's asleep, he'll read it in the morning.
Learning. He was born with hidden tastes that even he doesn't know. Every visit, gift, find and build changes what he likes, so his personality grows over time.
