I challenge anyone to add rotation :P
u/BirdsTweetCodersDweet

There already is rotation?
u/anotherkitten

i think he means on a different axis that would make the object look 3d
u/tomxor

Yup an axis that is not parallel to the camera plane... i'm half joking because it's an impossible object, a trick of 3d projection, that said their may be a way to maintain the illusion while rotating on one of the fictitious planes.

You use a trick that does not work on iPhone. In the HSL call you need a space between S and L.

u/Agnes

Consider using properly formatted HSL if you have the characters to spare - these all show up as 100% black on iOS Safari!

true, should have done, just habit to use the broken one
