Light Musings

So, I'm having lunch in the library cafe at the university (a most excellent place) and I happen to glance at the ceiling. And it confuses me. I looked at the arrangement of the lights and it seems that the person laying the black trunking to the light fittings has done things in a sub-optimal way. It seems to me that if the "cross piece" was one section further to the right, the wiring could have been a bit shorter and there would have been no need for the connections running across to the near and the far lights. 

If you see what I mean. 

Anyhoo, I pondered this for a while and came up with two possible explanations:

• the fittings were originally put in the wrong place and then fixed.
• Somebody decided that it was artistically more valid if there was a "fork" of cables. 

Personally, I really hope its the "artistically valid" explanation.
