Better Explained has a 'A Visual, Intuitive Guide to Imaginary Numbers' that's every bit as penny-droppingly fantastic as his guide to exponential functions and e.

Trigonometry is great, but complex numbers make ugly calculations simple (like calculating cosine(a+b) ). This is just a preview; later articles will give you the full meal...

Kalid's excitement for maths is infectious and I think this is because he gives off the impression that he's only just got it himself and is desperate to share this enlightenment with the world.

Absolute internet solid gold - this is the first time I've actually understood exponential functions rather than just plugging 'e' into a formula. The rest of the better explained site looks promising too!
