I LOVE IconPackager!! I change my whole computer theme about every three days. Here's my method (in order):
1. Install new WindowBlind
2. Install new IconPackage
3. Install new CursorFX
4. Install new SoundPackage (occasionally)
5. Install new ObjectDock skin
6. Install new SysMetrix skin
7. Install new Rainlendar skin
8. Install new weather widget
9. Enjoy for several days, then rinse and repeat!!!
