Can you see what it is yet?

Long, boring work day today. My PC is just about hanging in there but's running like treacle. Boss won't discuss it so I'm losing loads of hours restarting after a crash or waiting for a program to open!

This is my first effort for my texture assignment. Can you work out what it is? I don't think I will submit it as it was a quick on the fly effort to find a blip for today and I couldn't get anything more exciting as I'm not leaving the house.

Looking forward to the weekend. We have a 40th party tomorrow night so it'll be nice to catch up with friends and have my first drink in three weeks!
