The sign says it’s a university now. They couldn’t have done it without me…

The inside of the south-east pylon of the Sydney Harbour Bridge contains a museum and public access to the roof, so that’s where I headed today after breakfast.

It was surprisingly spacious inside the pylon, but then they were added simply to give the bridge an extra-strong appearance: they don’t actually contribute to structural integrity whatsoever.

This is a duck. And it’s in Cockle Bay as I type. And to get there, they had to bring Darling Harbour to a standstill. I just can’t write in words how amazing it is to see something so expensive, utterly pointless, and frickin’ fun all at the same time. The world needs more giant rubber ducks if for no other reason that it makes people smile.

Your turn, rest of the world.

Google Maps for iOS was released this week, and it’s lovely. It was accompanied by a blog post from Google directing readers to this page.

Tap-and-hold to do this, two fingers for that, swipe and shake for the other. Phew. Fortunately, not knowing the touch gestures listed on this page won’t impede daily use of the app.

These gestures are hard to guess, and there aren’t any visual clues in the app to guide users. I only discovered this page because I follow a couple of Google blogs: the overwhelming majority of iOS users won’t be aware that Google has published these tips.

I think Google are fine this time, but it highlights something I hope developers of human interfaces keep in mind as touch interfaces become even more prevalent: the very fine line between discoverability and usability.

Update: John Gruber’s comment on a post from Max Rudberg sums it up nicely:

A good rule of thumb is that the user should be able to figure out how to use an app just by looking at it.
