I think you're a bit confused, mate.
Electric Sheep is a sort of distrubed system that generates, downloads and plays fractal frames. It was inspired by the SETI project.
If you actually want to use the SETI program, the original version, 'SETI@home Classic,' stopped being used late last year (2005). The new version
is called 'SETI@home Enhanced.' Info can be found
here.
The new version is a program that can be run with
BOINC, a distributed computing program that actually evolved
out of the SETI@home Classic program.
