Might have been done before, but I didn't see anything under the barcode hashtag. Between u, t, c, x, S/C/T, and R, R looks the best to me.

u/fentbiggesthater it draws a barcode starting in the top left corner. Should be visible after a few seconds

Also I meant to say that I didn't see *this method* for making a barcode before, not that I'm the first to make a barcode. I could've worded that better 😅
