It's actually a little application that lets you get pictures from your Sprint PCS camera phone directly to LiveJournal. Here's how it works:
I take a picture with my phone and email it to myself. The client watches my mailbox for emails that contain camera phone pictures. When it finds one, it downloads the picture, then uploads it to my ftp server. Then, it makes a LiveJournal post with the picture and the caption that I entered when I sent it. Supa-fly.
It's not totally finished yet, but it's basically working and reliably posting to stevetest. If you have PCS Vision service from Sprint and a camera phone and you'd like to try it out, then e-mail me and I'll hook you up.
