"This seems to be similar in thought & approach to drivers watches, which feature an angled watch face for easier reading while driving. The concept is sound, but it does make one wonder if all of that extra geometry and material is really necessary or if there are perhaps simpler ways to angle a watch on the wrist..."

"Not for nothing but new technologies mimicking older ones is a very old concept. It's called skeuomorphism and has been around for thousands of years. The Ancient Greeks carved their stone structures to resemble the features of wooden ones that preceded them. More recently we saw the original iOS in which apps were often designed to mimic the physical item they represented (such as the notes app that looked like it was made of leather and paper or the voice recorder app that looked like an old-school microphone). And The Design of Everyday Things specifically talks about how the first automobiles were designed to echo the appearance of horse-drawn carriages.Skeuomorphism has always served the same purpose: to make the transition to new technologies feel more familiar. In this context, people may be more willing to purchase an electric car if it sounds like a gasoline-powered one, because the sound of the vehicle contributes to how "powerful" it feels. Without the sound, electric cars can strike people as weaker or less impressive than their more traditional counterparts."

"Probably because replicating natural human movement (or any natural movement, really) is incredibly difficult. We have hundreds of muscles interacting in a myriad of ways, and to replicate that motion with a few servos is no small feat. Not that robots aren't capable of realistic motion--Boston Dynamics' bots have shown significant improvement since their inception, and it shows--but it's a long road."

"How about just...temperature indicators? Most people with an industrial freezer probably want it set to a certain temperature, not just some value on an arbitrary and unknown scale."

"I wonder what the weight rating for those hanging edges is. Sure, it can hold three grown men standing within the support structure, but what happens if someone sits on the corner? "

"It's hard to argue with any of the decisions being made here because this is explicitly not a commercial project. As someone who has worn glasses for over 20 years, I would hate to have to disassemble and use a special case every time I want to put them away. But if Paul doesn't mind that, we can simply focus on the aesthetic choices. These are certainly an attractive pair of glasses, and there is something to be said about how thin the overall form factor becomes when disassembled."

"If slipping is a concern, I would think the higher- friction pivot of your fingers would be more likely to cause it. That said, even if a completely free-spinning bearing does somehow cause issues, they could still include a cap with more friction. Having just a hole in the middle to rotate around feels like something is missing, as if the design isn't finished yet."

"Add a bearing and some caps and it's a fidget spinner. Plus, that way it's easier to roll. Somehow this feels both over- and under-designed, which is a shame given the price."
