The 2D point-sprite editor
I used DirectX point sprites to draw the particles in my first editor. The controls let me change how they’re emitted, how they move, and what they look like as the effect runs.
When I added sinusoidal motion along the particles’ radial axis, the effect reminded me a little of Windows Media Player’s Battery. That experiment became the flow-field prototype for Trippendicular.

The later versions added a 3D camera, mesh rendering, configurable spawn shapes, and a dedicated panel for physics properties.

I experimented with classical forces between pairs of particles, using their mass and charge to change how they move. One saved preset, 3BodyOrbit.pfx, sets up three particles with gravity enabled.
