Sterile. The framing is boring too - generic-looking really, with the mat margins all identical in the first case, none at all in the second, just DIY-looking cheap flush mounting. Surprised the walls aren't Government Green, ala 50's. I suspect a lot of the art scene is running on fumes; needs some fresh air instead. And predictably, on that link, inkjet prints deceptively mis-advertised as "pigment prints".
I've never heard of McCracken before, but think I have a cat buried in one of his shoebox sculptures in the back yard, along with some catnip. At least those sculptures have utility, even though they aren't worth looking at. It's all been done before. Time to move on, to the next repeat prank.
