Wow! That's trippy and cool looking :D Looks like an oil spill or something #plasma #oil #oil_spill

Great!
u/tomxor

Neat, looks like #diffraction and #Interference, I guess it is litterally the later.
u/katkip

cool
u/Purpzie

Still seems to look the same without s.backgroundBlendMode='difference'
u/yonatan

Dwitter doesn't reset CSS styles when you edit the code. Try making it '' instead of 'difference'
u/lionleaf

u/yonatan Oh, I guess that's a bug.
