If you're not averse to having an LCD running some ambient geometry in the background as a way to jump start your brand, we have some FOSS for ya, but you'll need a geek or two to install it and boot it up, or maybe you're a geek yourself. I'll write as if you were...Grab and install VPython from Carnegie-Mellon or one of those, then grab my hypertoons generator, deposited at 4Dsolutions (we're like your memory bank of cool toyz).
If you want a podcast to preview, Synergetics on the Web has an example (narrated), or check YouTube for more.
Hypertoons are looping animation tracks with a network structure, such that you'll segue differently based on Python's pseudo-random number generator.
A hyper-audio track (matching or on its own) would be a logical next feature, feel free to start a project pointing back to its root. This isn't a visualizer, so don't worry about infringement (not a screen saver either -- wouldn't matter if it were).
You'll maybe be able to make your own hypertoons eventually, but for starters this starkly geometric one serves a didactic purpose (teaches philosophy), is family friendly -- is even interactive if your setup allows for controls.
You'll need some way to run Python. Maybe slave an XO to a ceiling mounted computer projector and shoot against some opposite wall?
I've not tried this particular option, am not sure if Vpython runs on an XO-1, plus why waste a perfectly good laptop for such a primitive purpose? Some junker with a gig of RAM oughta do the trick. Free Geek has those by the boat load (thx!).
Note: there's a stereo option but you'll need the special "glasses".
