[sudo-discuss] Pilfer/Theft Proof Money Donation apparatus for Free Store (and Sudoroom)?

Hi Sudoers: Now that the Free Store has to pay rent: can we design some sort of donation apparatus for them that can accept money but is not easily pilfered? My initial thought is some sort of large free-standing but heavy plastic tube structure (e.g. https://en.wikipedia.org/wiki/Dorade_box) but I'm open to other ideas. Bonus points: add some sort of fun sound as in this youtube video: https://www.youtube.com/watch?v=cbEKAwCoCKw We could make these for sudoroom and the fabric and textile area too. Anyone else interested in working on this? -Peter
