We noticed this lonely looking robot at the end of the right-angled cul-de-sac, Little Surrey Street, several days ago.

We snapped a photo, naturally, but didn’t quite get around to doing anything more. That is, until Kym Chapple tweeted another robot sighting in the neighbourhood.

He – has to be a he, right? – is on the corner of Craigend Street and Oswald Lane.

There’s something I like about robots in love. It’s part of the reason I love Mari Velonaki‘s beautiful robotic creations, could be the relic of a childhood reading Asimov novels. Whatever, I like it. More romantic robots.

For a moment we worried the chalk graffiti around the neighbourhood would stop when we put two and two together -i.e. when someone tipped us off (though we could have googled at any time) – and discovered the alphabetical riddler.

Fortunately, we needn’t have worried. This one – U is for “Unlikely” – is on Little Surrey Street, Darlinghurst, across from the Victor Chang cardiac research institute.
