I'm finishing porting our modern tools called ImageFX to Mac OS X. On Mac OS ImageFX use OpenGL fragment programs. Also i rewrite ImageFX core. Now it is more clear and better. New version will support Lazarus for Windows and Mac OS X. Also i start to developing shader editor - for easy developing of custom filters.
This is screenshot of Mac version:
This is new FXHouse - rewritten using VGScene. Now FXHouse called FXShow and available only as binary.
