This morning I worked a little on my presentation. I also, unexpectedly, participated in an experiment at the color science lab. I had to identify the important parts of 60 pictures. Some had many important parts, others did not have many. As a reward for participating, I got a brownie. In the afternoon, I went to watch Halle and Matt practice their presentation and ended up also presenting mine. I did not expect this, but it went well. There are a couple changes that I had to make, but they are minor.
