Presentation Brain

In the past two weeks I've given two presentations for STC events. I enjoy having the subject of practical sketching take up my brain while I write and update these presentations, and it reminds me of how I feel when I teach a class. They both take up a part of my brain that I think is normally filled up with sketching, because when I teach and when I work on presentations or art talks, I do way less sketching.
These are the only sketches I've done since last Monday, plus this one below of the garbage can under my desk. This was inspired by an Instagram friend who reminding me that I said that anything becomes special when you draw it.
Now that I'm done with my presentations, I should test my theory and see if I do more sketching!
