Contributed by Natasha Sweeten / There should be a word for the glorious sensation you get when you realize the art in front of you is better than you’d expected, having initially seen it on a screen. You may scoff, “Isn’t everything better in person?,” but I beg to differ. These illuminated contraptions we carry around everywhere are remarkably good at turning life to 11. When I’m rewarded with this aforementioned word-I-don’t-yet-have, I chalk one up for being there.  So it was when I stepped into David Hornung’s “New Work,” the inaugural exhibition at JJ Murphy Gallery on the LES.
