The visual series. Visual Complex Analysis and Visual Group Theory, for instance
Tristan Needham, "Visual Complex Analysis", beautiful introduction to complex analysis.
Tristan Needhams "visual" books about complex analysis and differential forms
Finally, I had a colleague, a complex analyst, try Visual Complex Analysis and he reported that students did not get it.
Personally I don’t think it’s ideal to use as an only book for a complex analysis course, but I found it very helpful for crystalizing my intuition/thinking about the subject.
A lot of great pictures, exerything is explained (and shown) geometrically. Complex differentiation/integration, non-Euclidean geometry, vector fields etc.
If you haven't read it, it teaches complex analysis in terms of transformations and pictures rather than solely algebra. It's very clever; Also touches on some concepts in physics and vector calculus.
Visual Complex Analysis is the best mathematics book I've ever read.
It brings a lot of (needed) geometric intuition to a field that is often very easily misunderstood.
