For those who want to spice up their video conferences and would like to use their iSight (or other webcam) with more than one application simultaneously, CamCamX might just be the app for you. Offering an old-school UI for mixing movies and images into your video conferences, CamCamX allows you to play digital broadcaster with most of the webcam-enabled apps for Mac OS X. In addition to mix-master-iSight with your video and media, CamCamX also allows you to use more than one webcam app at once, allowing you to, for example, hop into a video chat while also providing a live webstream or recording yourself with QuickTime (though, for some strange reason, you apparently need to purchase iChatUSBCam if you want iChat to fit into your CamCamX workflow). While the UI isn't the most beautiful thing this side of the HIG, it's a powerful concept that mimics Apple's upcoming iChat Theater in Leopard, but seems to open a few more doors since it works with apps like Yahoo! Messenger, Skype and even Flash.
A watermarked demo of CamCamX is avaialble from VJ Software, while a license costs $29.00, with 3-year and lifetime upgrade memberships available for $59 and $99, respectively.
