I've taken to spending a few minutes of my work day looking out the windows. Here's what I saw yesterday.

Pedestrians moving through the rain.

Looking toward Boston.
The column with the 1 on it is part the
Human Genome Trail. This is a depiction of chromosome 1 and is the start of the trail. If you follow the link and click on numbers it will give you a description of each chromosome.
At about 4 a flash of light caught my eye. In about 5 minutes time the rain had stopped and the sky had mostly cleared. This resulted in a lovely sunset. Here's one shot of it. This is looking back toward the MIT campus.
