Though image stabilisation and improved high ISO performance has greatly improved the low-light and night-time capabilities of cameras, these conditions can still produce shots with motion blur. Low shutter speeds may result in blur caused by camera movement, and this is not usually an effect that a photographer wants (though it can be, and it can be deliberately induced to good effect). On my recent trips through London's Blackwall Tunnel several of my shots taken there exhibited this kind of blur, and it prompted me to try for photographs with the other kind of blur - focus blur - as an alternative to the sharp shots I'd been seeking. I've made quite a few exposures in recent years with the camera deliberately out of focus, and I knew that the night-time points of light against a dark background had the potential to be interesting and perhaps beautiful.
The image above is the one I took that I like best. If you didn't know what the subject was you might not guess it, so you'd judge it solely for its abstract qualities - colour, shapes, composition etc, and here, I think, the convergence on the cluster of bright points of light works well in this regard.
