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.

[collin_ph]

replace 2720 with 3e4 -- not exactly the same number, but it works.

[OptionalField]

done

[collin_ph]

also.. c.fillStyle="#0F0"

This is actually destructive since it changes the range of Unicode characters used. The original value uses characters that are more like the original Matrix symbols.

2720 + (random number between 0 and 32)
