MoMA has an amazing exhibit on right now. i saw it recently and it blew my mind. it’s pretty much a sure thing you’ll see designs which will make you think “i totally thought of that” and/or “i can’t believe someone thought of that/figured out how to make that work.”
I highly recommend going. and if you’re not in going to be in NYC you can still visit the online exhibition- (but if you’re in NYC i promise it’s worth going. if you can’t swing the $20, $12 for students, it’s always free on Fridays after 4pm)

you may have seen this on MoMA’s promo materials and wondered what, exactly, it was. well! it’s a glass blown object that uses live bees to determine fertility cycles and detect diseases- including cancer. apparently bees have phenomenal odor perception and can be trained to target a specific odor (in breath.) – click here to learn more.

this is pretty much exactly what it looks like. indoor/outdoor furniture. i bet new yorkers are peeing their pants when they see this. – click here to see this object on the online gallery.

Merry-Go-Round Water Pump: the children spin around on the toy, pumping water into a nearby vessel. this reminds me of an exhibit that the MoMA put on a couple of years ago- Design for the Other 90% (of the, not affulent, population) I think it’s a great example of good design for a real need. -click here to see it on the online gallery.
