I’ve done a lot of projects over the years, and I’m finally getting around to documenting some of them

Four Legged Walker

Walking Mechanism

A four-legged Theo Jansen “Strandbeest” walking mechanism.


Color Science Projects

A set of topics relating to color science and colorimetry.

Sphereland Creatures

Vision in Curved Space

A study of how visual perception (especially depth perception) would change if we lived in a relatively small spherical universe.

Side View

Segway-Style Balancer

A low-cost, simple Segway-style self-balancing device made from off-the-shelf parts.

3D Shadowlamp

3D Shadowlamp

A device that casts 3D shadows.

light seeker

Light Seekers

Complex behavior of multiple interacting light-seeking “head” mechanisms.



Work I created after retirement while being a nondegree undergraduate ‘senior’ in the College of Fine and Applied Arts at the University of Illinois, 2010-2013.

UPS Time Exposures

UPS Time Exposures

A project I did with my wife’s K-1 class at University Primary School, Feb 2012.

Monomial Method

A numerical method for solving nonlinear equations, and the graphical investigations leading to my Design by Algorithm work.



BLIFNAR stands for “blinky lights for no apparent reason.” It is a device that charges in the sun all day and flashes eight LEDs all night. It is also known in the BEAM Robotics community as an octal “Pummer.”


Design by Algorithm

Jumps to my Design by Algorithm website. I exhibited math-based artwork at weekend art fairs throughout the Midwest for 25 years (1990-2015).
