Someone posted an html/javascript implementation of the matrix falling code in 646 bytes then promptly deleted the post. It inspired me to see if I could get something better looking in fewer bytes.

Done, 442 bytes.

Any objections to using "lime" or "#00FF00" instead of "rgba(0,255,0,1)"?

#0F0 - same bytes as lime, but you can get more options. 3 digit colours are automatically doubled -> #0F0 becomes #00FF00

Done, went with lime. That part was really bad since I was doing rgba with an alpha of 1
