All the colors of a sunrise

u/taupelink

nice!
u/rep_movsd

Try swapping around the r, g and b values - b, g , r and g, r, r look pretty realistic
u/rodrigo.siqueira

u/rep_movsd please paste the colors (q=...?) that you found so I can try your suggested combinations, thanks!

This one looks more like they're hanging from the top and moving around is making them shake.

Protein folding in 117 characters (extra bonus: view fullscreen to see ribosome α-helix spiral filaments)

magnificent
u/tomxor

So organic I love it!
u/rep_movsd

Brilliant
u/danny@hille.dk

The product is pretty, but the code is, while not easy to read, perhaps the most aesthetically pleasing code snippet, I have ever seen!
u/smtsjhr

is it a sufficient condition for the appearance of α-helix spiral filaments to just use 'α' character in the code?
u/DataMeta

this is amazing!! #organic

u/rodrigo.siqueira

Sure Smtsjhr, I think you also noticed that there is a β value responsible for the Beta-Helix (secondary structures in proteins, forming helical patterns of β-strands). I've just created a remix, changing "α and β" parameters to "lighted circles and donuts", as you can see in the remix link.
