Heh. Just being an idiot. But seriously - good stuff, Carnivac.
While the scanlines seem to add a "dirty" noise to the overall impression, they do also lend a neat old school-ish feel. I wonder if playing an entire game like that, with such visible scanlines, would become an annoyance after a while. Not sure.
Also, how would it even be achieved, technically?

As for all the scaling algo's - how would a simpleton, non-codin', graphic designer like myself put them to use in his own work?
