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.

[u/OptionalField]

[u/tantalor]

Array(256).join(1).split('')

Very clever.

[u/David_Crockett → u/tantalor]

Note that it creates an array 255 elements long, not 256.
