Portrait of Edwon, creator of Cyberquarium

Made by Edwon

Hi! I'm Edwon — former Disney Imagineer, current film director, and I also made Waba, the virtual pet for Apple Vision Pro.

I built Cyberquarium because I wanted it myself. I wanted a little fish tank living in the corner of my screen or on my wallpaper while I work — not just a gaudy sim of real fish, but something more fun, creative, and magical that reacts to music. And something to fall asleep to with music on at night. It didn't exist, so I made it — and it turned out cool enough that I figured other people might want one too.

It's just me here, so if something breaks or you have an idea, you can email me directly. I read everything.
