I need to let the user give me an Ethernet MAC address. FYI, that's usually represented as 6 bytes, printed as hex, with colons between them. For example: de:ca:f0:23:42:ac

Anybody know where I can scrounge a perl/Tk app to let the user input this? It's turning out to be trickier than I thought it would be.
