Agree. It's a fun effect to show off as a FE dev I guess, but it feels out of character. Maybe make a "party mode" or something? You could click a disco ball to turn it on! :D Other than that, cool idea and well executed.
I once helped conduct a hiring interview where the candidate had that enabled, it had an especially bad effect on the video compression in google hangouts screensharing.
There is a Real Terminal Emulator™ with some effects close to this (including, I believe, a nyancat cursor) called Terminology (from the Enlightenment folks).
Some of my colleagues use it and I tell them they're absolutely nuts, but they swear by it. It reminds them their code has meaning, I guess? Haha
