Now this is worth writing about. I just upgraded my version of Axialis Iconworkshop. They give free lifetime upgrades to registered users.

They've added a new feature called Icon Objects. This allows you to assemble your own icons from various image components, (e.g., backgrounds, highlights, shadows, symbols, shapes etc) and create relatively unique icons.

I've just played around with this, and I can say that any developer can finally create professional looking icons with a few clicks of the mouse. Not only that, create a full set of same-style icons for your app. It's fantastic. Worth buying for this feature alone.
