There is one particular feature that I have always wanted to see in Particle Fire, which is the interesting zoom-fade-glow effect, as seen in DX-Ball 2. Any chance this could be implemented in a quick update ?

They had a tech demo here at the time called Particle Toy. It showcased this technology. It was more of a toy and a technology demo rather then a screen saver which become the inspiration to Particle fire I believe...
