![A photo of a whiteboard titled: Ideals and Principal Ideals: Are all ideals in Z[x,y] actually principal?](/images/office-camera/2023-05-30T12:01:54-04:00.jpeg "Ideals and Principal Ideals: Are all ideals in Z[x,y] actually principal?")
There is a webcam in my office that I use to take photos of the whiteboard. This setup was inspired by Dror Bar Natan’s Blackboard Shots. You can read more about the setup here. If you know of anyone else with a similar setup, please let me know.

I’m working with Eric Vandendriessche and Alfredo Braunstein to understand a bit about how the string figure calculus acts of canonical linear sequences. This digram shows a simple example of the type of question we want to be able to answer.
The canonical start of a linear sequence is a point in nearest LFn string. In this simple example, there are three possible linear sequences (with the correct orientation) but only $L2, L5, R1$ has the correct start point.
My daughter Mira came in to the office this afternoon and coloured.
