Pardon my shouting, but HOLY CRAP THAT IS AWESOME!!!!
I've done a lot of work in the film days shooting product through huge magnifying glass, etc, looking for abberations and coolness. This looks amazing. I've already gotten quite good at 3D for printing (making a head-mounted HDMI monitor for steadicam work - badassery!!!) and this is intriguing.
However, this may mean I spend hours and hours understanding multi-element lenses, etc... I do the occasional music video...
What about printing an anamorphic lens?? See, there I go...
