A new release of mandulia (a zooming visualization of the Mandelbrot Set as many Julia Sets, with Lua scripting support) is installable from Hackage:
cabal install mandulia
You could also enabling additional optimizations, but these are known to break on some systems:
cabal install mandulia -ffast -fSSE4
(omit -fSSE4 for CPUs that don't support SSE4 instructions).
After you have installed it, you can try it out by running:
and hit the 'a' key to enter attract mode or use the key controls listed in the README for interactive navigation.
mandulia-0.7 has some small visual enhancements, including reduced jitter for smoother animation (at a cost of one frame additional latency) and minor new features including accessing runtime statistics from Lua scripts. mandulia-0.6 (if you're wondering about the version number jump) fixed the small bug mentioned in the release announcement for mandulia-0.5.
