Spontaneous Ideas

This is a place for spontaneous ideas that I or others have, which have a measure of sense and usefulness, but which the poster is unlikely to pursue due to time or inclination. For me, mostly time. If you like the idea, take it and run with it. Please be kind enough to cite the post you used and/or tell me if it provided you with inspiration or proved helpful. Don't worry, I, and anyone who post and idea, won't sue, but we may ask to help. It is how you execute it that counts, not the idea. If the idea already exists, then please tell me so I can use it. Now, go make something useful!

I came across this mug while having lunch with a friend. I immediately thought about what would they do with the mug if one of the advertisers decided not to continue advertising with them. Would they cross out the advertisement? This of course got my mind working on a solution to this, likely minor, problem.

One possibility is to embed an e-Ink display on the outside of the mug, since they can bend, and update the advertisements wirelessly. You could charge the mug using the new wireless electrical systems that are appearing now. Too expensive at this time, certainly, but perhaps not in the future.

However, cleaning these mugs could be a problem…
