#Unicode code point ⇄ char converter : left is code point in decimal 🔃 right is character : useful for copying individual combining marks #tool

u/metamero

use ctrl-a then ctrl-c to copy the combining mark on its textarea. then you can it use by pasting after the character you want to modify. once a character is modified, often you can't select just the combining mark anymore, so this little dweet can help to choose and select diacritical and other combining marks. you can try all unicode range e.g. 휂 55042 U+D702. zoom in ;)
u/metamero

focus and edit any field then click out of it

how does this work!?
u/KilledByAPixel

it is a cellular automata, each frame it tires to move the snow down and left or right randomly if the target cell is empty
u/Odog8

oh wow
u/tomxor

Wow nice! it's great how an effect can take on new meaning when finding a different way to frame it.

cool effect - but at the same time scary to think that this is what my incurable cancer could look like, which unfortunately is slowly but surely spreading and seems to be gaining the upper hand.
