For those in a mathematics learning frame of mind:
This is a worthy two page paper on resources to help teach yourself math http://hdl.handle.net/11299/42385

I wonder if there are more current aids? If you know of them (like Kahn Academy please share)

The Jastrow illusion is a size illusion where two curved shapes of identical measurements are placed next to each other. When viewing the two shapes, one looks significantly larger than the other. When the positions of the two shapes are reversed, the impression of which is the larger is also reversed.

The study of perceptual illusions like the Jastrow illusion helps scientists to investigate the various mechanisms involved in the visual perception of objects, and thus increases our understanding of how our minds function in informing us about the environment.
