Quoted from herg:Thanks for the link. That does look promising for something functional.
What about something decorative/custom? Maybe a WOZ related item with a hole in it to make it harder to press the button? Unfortunately, the only ideas I can come up with are funny, but not family friendly.
Hooked is making something for MM and it's really nice, maybe he could come up with something for you and other WOZ owners. Give him a shout.
