iOS NSData byte Access

The docs say the data is not cached when imagewithdata is used:
http://developer.apple.com/library/...ml#//apple_ref/occ/clm/UIImage/imageWithData:

There is another method "initwithdata" I can compare with.

Bitmaps can indeed be written upside down so the iOS gfx orientation fixes it for free.

Lol, it got metadata rejected.. I think that is for calling a demo a demo?
Maybe a wallpaper would be better?
They said the word demo suggests it's a trial version, etc...
When in fact it is a demoscene demo

It made it and source is available:

It's so inconsistent across devices, I'm surprised it made it,
and I plan to hide it in a small country so that it's not largely available,
and if I improve it, I can dodge the review process for a new app.

I should have created a bitmap context and manipulated that,
rather than writing to a bitmap file, and making iOS interpret it every frame.

Then I think you would get the 60FPS for a pixel based 2D drawing app.
The demos are PD, and I disclaim any right to the iOS template.
