A remote pet feeder with camera.
The downside is of course the cost, nearly $300! and I guess there's also the security problems of allowing remote access into my home PC to monitor it. (Something I don't do now, so it could be a big hassle getting through all my firewalls and traps and stuff).
Still, how neat would it be to see the cats every day when I'm away! and know that they have food and water. (and haven't burned down the house!)
Better stop before I talk myself into it!
(footnote: I hate when I run spell check and it finds nothing, I'm such a poor speller that I never believe it!)
