What is it?

Can you guess what this is?

Bad start to the day with being late to work (partly due to this photo) and being told with no minutes to spare that I couldn't have equipment I'd asked for for a lesson. Then I was undermined by another teacher in front of a class which made me very angry but I couldn't do anything about it. Most of the day was good though.

Oh and I've lost my voice :-(

edit- just looked at this on the computer and I'm quite impressed with how good a job the phone did.
