FYI: This dweet looks different to me, depending on whether I'm viewing it on iOS/Safari or on Chromebook/Chrome. On iOS, there's more detail even in the dark areas. I'm guessing it reflects a difference in how the 'hue' is implemented, but I dunno.
u/sigveseb

Awesome! Love dweets that expose browser implementation differences like this. Looks cool too :)

Okay, this is a bit cooler than the earlier one. Thought I had more colors in that first one.

As you can see, the server might go down a bit soon. Also, it went down by mistake for a minute or so just now. I hope no-one lost a dweet! :( Sorry
