John,

I've seen this in the public domain as either javascript or a java applet, I know I have - I even played with it once way back when but i cant remember the name. And I just spent 5 minutes looking thru my favorites and came up empty handed....

go to jars.com and search on "menu", could possible show up in a couple different categories. Since I found it before, you got 99% chance i found it on the jars site.
