Repurposing a baby monitor...

Here's some ideas I've had today for repurposing a baby monitor. As we're nearing the end of our needs to monitor our babies, we'll need to find some alternative uses:

1. Homegrown radio show
2. One-way intercom ("Dinner's served!")
3. Halloween prank (put receiver in dummy on porch and "boo!")
4. Sleep aide (when set on alternate station, whitenoise!)
5. Eavesdropping (general purpose spying)
6. Parent monitor (reverse engineering)
7. Seance (hoax)
8. Poor man's walkie talkie
9. Pet teaser
10. Hearing aide (a bit large, but effective)
11. Drive thru ordering (isn't this the state of the art comm system they use now?)
12. Synthesizer (when waving the receiver next to the monitor)

I welcome additional ideas...
