Update Aug. 25, 2015: I've replaced the script with a new one that allows you to add/remove spinners. It appears the earlier one that was posted was incorrectly edited and didn't work properly. -jeff.perkinson
Bill Worley billw@jmp sent me a spinner script that the SEs use to generate a random number from 1 to the number of people eligible to win something. We use it to give away JMP books. After you run the script, simply type the maximum number (How many People?).
After you type the maximum number, the spinner pops up, you hit spin, and then the arrow lands on a number and the value on the spinner displays above the spinner.
