Okay since some of you asked in the show off section how I did the aninmated sigs heres one way I do them. 

Things You'll need
1) Adobe Photoshop
2) Adobe Image Ready(Should come with PS)
3) Quicktime

First here is the outcome.. Pretty basic design but this is more about getting the animation in the sig then the sigs detail.
