Talking kitchen-trash can burps when it's full
An NYU student is planning to build an animatronic trash-can that extends the functionality of Walt Disney World's talking trash-can:
The trash can and recycling bins are a modular set that would gives both sound and visual feedback. The trash can would only make a sound when you open it (i.e. open it's mouth). For example, when you throw something out, and the can is near full, it can belch. When it gets very damp (using a moisture detector), often an indication that the trash is more prone to germs, smells, etc., it can cry. When you open it up to take out the trash, and change the liner, it can giggle, as in being tickled. The sounds don't need to be so human, animal, or literal. But, with the sounds, the trash can takes on some "creature" behaviour.
