"I understand the intent here, but I see several limitations, other than the ones mentioned below.  First, the color difference between 50% tight, 75% tight, and 100% tight is barely discernible on the computer screen (see their website), let alone in an industrial setting.  If the torque of a bolt is important, a savvy and smart mechanical will double check the bolt torque using a more-reliable torque wrench.  Second, dirt and grease are going to get into the indicator port, causing a potentially false reading of black - 100% tight, A-OK, bolt is fine, nothing to see here, move along.  Finally, the upper temperature limit of 168F is not that high a temperature for industrial applications.  I assume temperatures above this limit will melt the costly plastic indicator in the bolt."

"Geez - Just sit on a log."

"Interesting... I like Marc Newson's work - love the carpet design, the shower, the door-frame and paired windows,  but, without being too critical, I noticed a couple of details in the pics above that jump out as being a bit sloppy for a mid-level designer, let alone someone like Mr. Newson.  First, what is going on under the "desk"?  I understand that the plane has difficult shapes to work with, but those lines look horrible.  This just looks like someone overlooked the detail during the design process and had to force fit some already made parts during installation.  Second, the "control panel" on the seats do not fit.  The panel is rectangular in shape while the recessed surface supporting the panel is trapezoidal.  It looks like they took an off the shelf control panel and stuck it on their already designed chair.  I think a trapezoidal bezel on the panel matching the chair would have worked better.  I know, I know, very picky, but details matter.   Also, the large table looks blah."

"Looks like a lot of design effort to hold just three pens.  I guess function follows form in this one."

"Won't the center of mass change as the plant grows?  What if a branch grows towards the cork and shifts the C of M to cancel out the 'balance' feature?  Just sayin'"
