"From a design study point of view, I appreciate the questioning of convention here... but... the practical side of my brain is asking "If he is using the momentum of the stairs to move in that way, what happens when he reaches the top and then has to stop an entire staircase from rotating to be able to step off?"Perhaps it's a game... you walk to the top and then keep going, fast-tracking your decent, ready for you to start over. Perhaps this is more useful as a slightly painful human exercise wheel."

"Nice concept - although the direction of force application may make things tricky unless accessibility to the socket is perfect. The irritating thing is that, we have reached a point with some of these consumer products (the charger in this case) where the ergonomics have been compromised on so much that those products have lost some of their core UX functionality, and now require more single function products to regain that lost functionality. I love the apple design language - most of the time - but I feel that they prioritised compactness too heavily with this charger block, without putting enough emphasis on the usability when it comes to removal.I get the justification... "Only a small proportion of interactions with this product will be for removal, therefore we can make that a lower priority", but I think even a 2-3mm increase in width would have allowed the additional space needed for slightly larger, deeper grips. "

"Had to have a go at this!How about a two footed arrangement? Stand on the base of the unit and lift either foot first and step out of the boot. Doesn't matter what order, and you never get a dirty sock... Naturally a bit bigger but I like the form... perhaps a steam bent ply construction?"

"Had to have a go at this!How about a two footed arrangement? Stand on the base of the unit and lift either foot first and step out of the boot. Doesn't matter what order, and you never get a dirty sock... Its a bit wider, but I quite like the form - probably a steam bent ply or something along those lines."

"I agree - I think there is a time and place for each method.Even though I 3D print hundreds of parts each month, I still love to see this method as it brings a bit of old-school craftsmanship back to the practise - which I find quite nostalgic... and it gives me a warm fuzzy feeling :D"

"To me, it looks as though it would be unbalanced in some orientations. Big fan of the versatility though!"
