I got it running but it just takes too much space. (454 mb).
Rather use that space for my Filter Forge files...

Yeah; the compressed downloads over 100MByte (the version I had a year and a half ago was a little over 80MByte). You have to understand that it has to be able to execute Wolfram's program. Is it worth the download? Depends. Maybe Saul can get his Script-fu to create the Maurer Roses and then others might think the other cool things the Wolfram Player can do won't be worth the download.
