Here is a sample of some of the branding and logos I’ve done in recent years.
Ceviche provides electromagnetic simulation tools for solving Maxwell's equations. The red and blue in the logo signify the peaks and troughs of the optical fields this package simulates. These colors are commonly used in physics imagery to depict waves.
Named for “Adjoint NonLinear GRadients,” Angler is used to optimize optical devices. The colors represent the performance landscape it optimizes over.
Here are some other, less terrifying, alternatives.
Legume is named for its use: “le GUided Mode Expansion,” which is why it is a soybean pod.
