Text positioning tweaked on a Chrome on macOS, so may look screwed up on other browsers.
u/magna

Also, holy shit. Look at those artifacts around the skunk. Who at Apple cleaned that image?
u/magna

*Apple -> Chrome/Google? I don't know who is responsible for the emojis :)
u/mxfh

Lol. Apple Skunkworks I suppose. dwitter is a whole argument while real other browsers should be enforced to be allowed on iOS.
u/rep_movsd

Safari/webkit is the new IE in terms of browser stagnation and bugs, i come to dwitter to not care about it :)

First thing I thought of when I saw Yonatans! Such a great team effort, the original idea, lots of golfing and these two finishing touches.
