Those that would like one for their car can try here. Never used them before but they seem to know their stuff.
I think a little flyer with the logo on top and then a blurb beneath it would work just fine for raising awareness. Sticking them between the blu-rays would do it I think.
Another idea I like is to create a QR code like TheoOdo suggested and have it link to a short video people can watch on their phones that briefly explains what this is all about. You could post these near the the blu-rays possibly using adhesive putty so they'd be easy to remove with no residue.
