Ahhh memories..many years ago, learning the tput capabilities, I knocked this together. Yes it is crappy code, but I keep it for sentimental value - not for the popular dance it represents but for the nuisance value it had to a friend and co-worker (it used to trap and ignore control-C and found its way into his .profile if he forgot to lock his screen). It is benign but of course never run what you dont understand and trust. Never ever. Ever.
