This was supposed to be a yellow pepper by the way, not a banana :(
u/Billedluh

This is a masterpiece. But I really want to see the other side of it can you make it go all the way around plz
u/KilledByAPixel

https://www.dwitter.net/d/9218 a banana like yonatan's that you copied from?
u/SockTaters

Welcome to Dwitter! You can directly edit the code of a dweet and press "Post as remix" to give credit. The way you did it is frowned upon.
u/vchoulga

Yes! It was inspired by Yonatan's! I wanted to make my one type of fruit/vegetable!
u/vchoulga

u/Billedluh

Now I feel dumb for not knowing about "the #banana frenzy of 2018." Also I do wish there was a way to denote something as a remix after it's posted, I've made that mistake before too
u/joeytwiddle

How about a fiery green chilli? fillStyle=R(b=20+20*S(i+5),b*5,a=0)
u/fentbiggesthater

100% stolen, should be punished/removed
u/tomxor

Not quite, It's exactly 90% of Yonotans by characters, 12 constants have been modified, 1 removed, 1 added - It's a derivative, which is fine, we like remixing on Dwitter, it just needed attribution is all.
