Michael great job as usual, thanks for the OSX version. I am currently testing it on an iMac 24" OSX 10.7.2 2.8 GHz. Core 2Duo/ATI Radeon HD 2600 Pro 256 MB/4Gigs ram. It runs great so far with a few exceptions the app will not hold any customized settings like full screen on launch, UI size, grid colors, show axis icon it reverts back to the default settings on start up. I normally run Moi on a 2008 macbook unibody via Bootcamp and Win 7. I look forward to testing it on the Macbook when I get back home. I will report back. I have attached some test images. The flow worked like a charm, the array started to slow things up a bit but I suppose that is to be expected.
