What I really want to know is what Shelley was looking for when she stumbled across this: an art project to collect 1000 liters of human sperm and display it in a transparent cube. The Sperm Cube does not look like it was well thought out, I’m afraid.
One problem is the collection method. They just want donors to ejaculate into a vial, and mail it, unrefrigerated, to them. Would you like the job of opening tubes of rancid semen and dumping it into the cube?
Another is the health risk. Human fluids need to be treated as a biohazard—they can be ripe with nasty pathogens (HIV? syphilis?), and they do seem to be rather indiscriminate in who they’re accepting donations from.
Now look at the design. They’ve got a 1 meter cube full of a viscous fluid on top of their cooling element. Does that look efficient to you? There’s going to be a damp, runny slurry on the top and sides of that, and nothing will increase the visual appeal of a giant lump of frozen sperm than thriving multi-colored colonies of bacteria and fungi growing on it…unless, maybe, it’s nice squirming masses of maggots tunneling through the semi-congealed mass.
Do they have a disposal plan? This is not practical as a permanent display, and at some point they’re going to have to turn off the freezer and do something with the gunk.
I suspect this is a case where an artist really should consult with a biologist and an engineer before charging off into an insane project.
