Found in Bunda Street today, though by the looks of it, it may have been there for a while. I walk that way most days but I can be pretty unobservant. Luckily I had the camera out in my hand (it's always in my bag), which tends to change all that.
From across the road the Apple logo shape was pretty convincing - at least at first glance - then I had a closer look:
It's a collage made of Scientology leaflets. The Scientologists have a big tent set up in Garema Place this week, and I was kind of surprised to see some people in there apparently succumbing to the "free personality tests" et al. I don't know if the timing of this art was deliberate - hard to even guess, given that I don't know how long it's been there.
So, you want to know what it's all about? There was an artist statement right beside it.
