height of creativity/joblessness!!

My roomie just asked me something about some calculator(calc) functions, and that brought back long lost memories :), as first year students, our particularly favourite passtime was to write messages in the calculator (starting Fx 911 W , i think A-F and several other keys are present) , and our inventiveness provided for the alphabets that couldn't be , so a pi became an r and so on (try it!!) ..
that was a really cool/creative/jobless thing to do!!
ok, lemme get back to work.
