It's no surprise to me. Even launching an edge down a coax
and watching the reflection back from the discontinuity
is wonderful!

One step further, and trapping the reflection of a
strobe lamp with a telescope and a photocell or pm tube would
be a magical experience for suitably disposed kids, I imagine.
Another step, and its a detected moonbounce with microwaves.

Has anyone looked for a reflected supernova flash off adjacent
stellar objects? (It would have to be a glancing reflection,
I imagine if one had the ..er.. 1988 event in mind?)
