One of my favorite Adobe products is Kuler
, a Flash-based online tool/community for picking color palettes.
There's also an (unofficial) Kuler screensaver. Windows
(here's a different version
). Pretty much requires an always-on internet connection (not that it moves a lot of data--but without the net connection, it'll just show the same combination of colors over and over--needs a cache or something). If you use a screensaver, you might give this one a try. I find these kinds of things simultaneously soothing and stimulating.
If you like this stuff, you might also enjoy, among other things, Plastic TV
(similar stuff here
), Grass Collective
and some of Brian Eno
