OK I admit it's not the most exciting picture ever taken, nor yet the best composed but there's a reason for that I'll come to in a minute. What you're seeing here is a series of LED flags and like those maritime flags they're supposed to some special meaning, in this case it's a relationship with local groups or places. The sign below gives some sort of an explanation and also the reason why I couldn't take a better picture. The lights are controlled by the wind and within a minute of taking the picture they all went out.
Hmmm. Anyhow there's a webpage with more about this (including a short video) written by the very man who thought it all up here.
