Emergency Blip #2

One of those little seedlings I blipped a few weeks ago has blossomed! Not bad for something free from a smoothie packet! More marking tonight and haven't even started on the second batch of reports, grrrrrrr.

On another note, I tried cleaning my sensor tonight. The bloody blower just seems to move the dirt around and I'm too scared to do anything else to it. Not happy, how did it get so dirty?
