Time lapse on the loose without a tripod

I really don't have a lot of technical knowledge about photography, I'm happy just to 'play' (for now) and luckily, I'm a fan of accidental images.

This is what happened when I tried to take some photos of the Sydney Opera House at night, using a slow shutter speed and no tripod...

The last one, especially, reminds me of a fluffy feathered nest!

Local graffiti

This abandoned shopfront sign on King Street was a perfect canvas for a stencil artist.

Took these photos a while ago, so not sure if it's still there, I guess street art is always changing.

The peeling vinyl sign has different shades of blue and white, faded lettering, splatters of paint, lots of imperfections and details.

Maybe it doesn't look like much at first glance, but once you start zooming in on something like this, you 'find' so many different compositions.

Here are some of my faves...

Does anyone know this artist's name?
