Not all cool ideas are actually good.
Back in 1983, around the time the IBM PC made its debut, my boss at Intel had acquired a very innovative personal computer: the Hewlett Packard 150.
I remember it well; it was a really cool machine – at least in the context of its day: it had an 8MHz (yes, 0.008 GHz) CPU and 256KB (0.000256 GB) memory, as well as two floppy disks of 270KB each. It also had that solid look and feel that the better companies gave their machines when they could charge thousands of dollars for them. But what made it super cool was the screen, and the ad here shows you how proud HP was of developing it:

The HP 150 had the first Touch Screen I’ve ever seen on a commercial computer. It was actually a regular nine inch green CRT, with a bezel that had holes all around it with IR emitters and detectors in them; sticking a finger at the screen would block some IR rays and tell the computer where you were pointing. And this is where the designers had failed: they forgot that the human arm is not designed to be held in the air, poking at a surface in front of one’s face. The resultant muscle fatigue was known as Gorilla Arm…
That alone was enough to relegate this screen to the junk heap of failed ideas, and touch screens would have to wait for tablets and devices that can lie flat on a tabletop or be held in one’s hand.
Still, you have to admit it was a good looking machine!

So, here we see a layout that has disappeared without any living descendants: an extinct primordial denizen of the keyboard universe. And for good reason: the standard location puts the arrows nearest the user, where the CompuColor II had them farthest away. It’s bad enough that the mechanical issues of old typewriters forced on us the QWERTY layout, with the most used keys out on the top letter row; since those typewriters did not have arrow keys, there is no reason to apply the same counter-ergonomic approach to them too!
One of the first scientific facts you learn as a child is that snowflakes, those lovely art creations of nature, have a six-fold symmetry. And they do; the properties of water molecules see to that. Hence the standard symbol for snow (and freezing, and cold in general).
So here is the right way of doing it! The sign to the right (found on another level of the same car park, strangely enough) leaves no doubt whatsoever: cars should exit to the right. I don’t remember if they had a similarly unambiguous sign for pedestrians, though those are usually marked with a running person for safety reasons. Anyway, isn’t this simple sign design convention something that every parking structure in the world should have?
