I already saw his lightning pics - the second one on his site is maybe a bit blurred but looks great. I used way shorter exposures - 8 secs for my pics, surely lots of clicks go wasted!

It is lightning and the context is shown below.
I haven't taken lightning photos before and these stikes were so far away that no thunder could be heard perhaps 10-20km so detail is poor. At least it wasn't raining.
The sea shot were taken on the same night from a similar distance.

The best lightning show I have ever seen was from the 49th floor of a hotel in Melbourne. It was quite captivating as it moved across the city with very frequent strikes and the view was very clear.

Looks like a closeup of the rebound after something (probably water) was dropped in a pool of water.

It is a water droplet travelling down in the picture. It was taken as one of about 300 shots I took while doning the Water drops walk uphill thread.

The drop is distorted as it has only just broken from the dropper tube. The streaky lights below it are the shutter which at 1/60 sec is still open long after the flash has taken the main shot.

Photo shows the context.

I've scribbled over this in a paint program - right?

I'd say you scribbled over it with a powerful red laser, in real life. Probably a long exposure shot at night.
