Good idea.
There's a developing trend for ultra-shorts (or maybe it's just that I've been noticing them more recently) and those taken from unfinished projects can be almost as good as those made specifically for the purpose.
Almost.
Whilst impressive, and great fodder for a showreel to show prospective clients for a quick burst, it's not /as/ entertaining as Channel Surfing 3 for obvious reasons. Rather than the focus being on diverse styles, short excitement, jokes... it's simply to show off the pretty pictures.
Which is a good thing in itself but I don't consider it quite accomplished enough to stand on its own simply on grounds of technical work.
My primary gripe is with the cutting - cutting to the beat imo would have resulted in a more exciting watch and more of a 'wow' factor.
Of course, this may not have been possible for you...
In any case, I certainly agree with the motives. Better to show this stuff off than to let it never be seen.
