This is Aperture4D as of 2011-Jun-21

Copy the directory (at least aperture4d.exe, font.dat and a valid input.txt) to your local machine to run.

Requires Windows and graphics hardware (GPU) capable of at least OpenGL 2.0 (the code will tell you if not).  It likely will work under Linux using WINE and Mac OS X using the WINE component of WineBottler.

Press Q or Escape, or close the window to quit (S takes a screenshot).

It includes multipole kicks, but not yet any thick elements or skew multipoles.

Performance degrades a bit if you put too many different iterations output levels (dozens).
