Econ Technologies has released an updated Universal version of its ImageCaster webcam software.
ImageCaster 2.1 ($30) runs natively on both Power PC and Intel based Macs. The software extends what your webcam (including iSight cameras) can do: images can be captured, edited, captioned, scheduled and more through an easy-to-use interface.
Additional features include smart window staggering, updated graphics, updated online help and several bug fixes. A free demo is available online.
