Quartz Composer - VJing Potential

The other day i stumbled across Quartz Composer. For those of you who don't know, this is a modular programming interface that lets you manipulate images/videos etc. It makes good use of Apples core image and video libraries, which would otherwise remain rather intimidating technologies for the casual programmer to harness.

After a few hours of playing around, adding filters to my iSight, and creating flashy screen-savers i decided to create a simple composition to wish my father happy birthday. All went smoothly and it was received well by the said recipient.

However, this got me thinking. Recently, DJM was complaining about how expensive VJing software is, and how taxing the programs are on the computers memory and storage space. If-someone was to code a new VJing software for Mac, which made use of all these free, built in and very powerful OSX technologies. The resultant program would be relatively small and could be priced quite modestly (or just for free).

When i get good enough at programming, i might be giving this a try.

Quartz composer is free with Xcode.
