I made a website where you can draw a fish. And you can watch it swim around. If you're interested in it. I spent a lot of time on it and I'm not really sure who to share it with.

http://drawafish.com/ if you are interested. would love to hear your thots...

If you can show me the console outputs I can take a look into diagnosing why ! It's possible it's just very slow

when I click the button I get this

On initial pageload I get this

so some wasm features might just not be supported?

Yeah, that must be it. There's a CNN I trained that runs in the front end and shows you what percentage fish it thinks it is. There's also one in the backend, so I could honestly catch the error and let ppl submit without the front end verification. But then it kind of fails silently which isn't good UX... maybe I'll do it in the morning 😇
