Silly little toy

Allows you to zoom in as deeply as a cheap 1950s toy microscope.

Nice rendering but limited

Portrait mode only on iPad, and performance is less than what I'd expect. Seems like it's using CPU calculation rather than any leveraging of the parallel capabilities of the GPU. Good quality rendering though.

Beautiful icon!

I love this app but the image seems squished horizontally. Is there any way it can be stretched back normal???
