Oh, don't worry, there'll be a damn good reason for it, one that benefits Apple - lol

Sounds cool, but they're all trying to get in on Linux now, even Microsoft plans to release Windows 10 (for free) for the new quad-core Raspberry Pi,
no doubt hoping they can eat their way into Linux territory.  Unfortunately for them, I won't be installing Windows on mine, nor will anyone who is wise :-D

Anyway, thanks for your help with this, it does look cool and I look forward to playing with it soon (and I love the way Lux handles light calculations)!

This first thing I'll be doing is trying to get it to do Anamorphic (stretched) bokeh.  I read it can be done with Lux, so I'm hoping I can get it to do that somehow through Reality as well, probably by sticking a 'cutout filter' in front of the camera.
