Plasq today announced the availability of a set of 10 free “sqreensavers” for Mac OS X. The artistic sqreensavers range from abstract vector colored shapes to panning pastoral scenes, and are based on the larger set of visualizers from plasq’s “Rax 2.0” application for professional musicians. They have been designed to use the graphics power in modern machines, resulting in attractive visuals at relatively small cost to the CPU. The design of the sqreensavers, based on Apple’s Quartz Composer technology, requires Mac OS X 10.4, and function best with Core Graphics Accelerated video cards.
