Two images (24″ x 30″) painted with india ink on book paper.  The book paper was first adhered to a painting canvas.

These are Finite-Difference Time-Domain (FDTD) simulations I've created in MATLAB. The modeled structure is a rectangular resonating cavity with perfectly conducting (PEC) walls. 3 Gaussian electric field pulses are defined at variable points in the cavity and propagate as electromagnetic waves. Two different discretizations of the computational domain are shown the two different pulse widths. In the code these are all variable along with all other parameters.

​The simulations presented here are animations of the z-component of the electric field on a horizontal slice at about the midpoint of the z-axis, giving a sample of the x-y plane. Since the walls are PEC it is seen that the z-component of the E field is identically zero at the boundaries.

Proxie is a tele-existence robot I am developing.   It has a ways to go, but you can see it in action here:

A mural of the Eiffel Tower in perspective I did in my dining room.  It’s roughly 7 feet tall and took about 12 hours. It’s done in black wall paint with a standard house painting brush.

A mural of Einstein I did on my garage wall (I went a little Jackson Pollock at the end...)
