If you have not tried these, they are wonderful. My little girl just loves them. They are very inexpensive to make (under ten dollars if you have spare 12 volt power packs laying around) and very easy. No soldering unless you just want too. While sitting here waiting for my phone to ring, I strung up 4 flies in under two hours.(we had a trial and they were convicted-this IS Texas) Search for "fireflies" on the Monster list of Halloween projects and you will see the link to the instrucion page by T.R. Shaw. He also sells them if you don't want to make your own. His web site says they will not be avaialble until later in 2003 due to him redesigning them. I think they work great now, can't wait to see what he is doing to modify them.
