Plant a world. Find something odd. Help us work out what makes it interesting. You can spend all day in the lab without joining the compute network.
Try a starting world, watch it unfold, then poke it. If something surprises you, share the starting world, seed number, settings and step through the issue tracker. A screenshot or a saved copy helps others take another look.
An island is a browser tab that lends its GPU: it runs segments of queued experiments (a stretch of one world’s history at a time) and sends the results back for comparison. This is today’s compute network; the persistent garden with creatures migrating between visitors is a future direction. The lab’s Four islands world plays that idea out inside a single jar: four islands trading a few cells.

Opening the island page starts nothing. Pressing Join asks the coordinator for work. The tab may use a lot of GPU time and power while it runs, so expect a warm laptop and a busy fan.
Press Stop or close the tab. Finished work and uploaded results stay with the coordinator. The privacy page lists exactly what is sent.
Ready when you are
It shows its connection and what it is doing. You make the final Join choice there.
Availability depends on a configured coordinator. If it is offline, joining fails without starting a simulation. Read the privacy details before joining.
