Description:
"Lepton is a high-performance, pluggable particle engine and API for
Python. It is designed for creating graphical special effects for
games or other visual applications. The engine is designed to be very
flexible and does not rely on any other libraries directly. You can
use it either with OpenGL (via pyglet, PyOpenGL, wxPython, etc), or
with pygame by selecting the appropriate renderer. Examples are
provided using pyglet and pygame."
