My application is a GridComputing application that interfaces POV-Ray (http://www.povray.org/) with the framework JPPF (http://www.jppf.org) . With my JppfPov you can use the potentialities of a gridcomputing network to make rendering task.
JCGrid is an easy-to-use tools for real-world grid-computing. It requires only to install Java Runtime and you can easy split your cpu-intensive task among several Workstations/PC/Mac/etc. It includes support for POVRay and MandelGrid as usage examples.
