And now for something completely different

Usually I’m not really fond of graffiti. At best, it is annoying, at worst it is just butt-ugly and ruining nice buildings.

But in a basketball-court in the park near my house it didn’t disturb me at all. I thought it was fascinating, especially the colours.

And what’s more, I finally had time to take pictures. I miss photography so much!

As for the meaning of it, however, I am left totally clueless.
Are these works of art, or just idiotic expressions of restless teenagers?
