hsmyers: as a pioneer I really appreciate your input! I was planning to run godelbrot on my Pi, so I will definitely check out your venerable FracZoom program for RISC.
*However, *drawing an outline box is exactly what earlier versions did. I found that people just couldn't figure it out. What happens is that they would click randomly a whole bunch of times. Then they would zoom into a tiny area of space, and decide my program is broken. No-one even noticed the box until they stop panicking. By then they're looking at a large area of nothing. *It was really unintuitive.* The reason is that there is no conceptual mapping between the mouse pointer and drawing a box to zoom a fractal unless you have seen it before. So I started looking for a conceptual map. I came upon the following realisation: With a box, small clicks = massive change. Long click (dragging the box) = small change. With my evolved method, small clicks = small change and long clicks = big change. I know that a bunch of different fractal programs use the box method. Arguably, it is more efficient *if you already know about it*. You are correct though that the box should stay up on screen; there should be a progress indicator. This is covered in the following issue https://github.com/johnny-morrice/webdelbrot/issues/10 I actually really like Pierre Durand's interface. The digital zoom effect is very nice. I'd like to move to that some time. However, there are tonnes of interactive-focussed renderers in the vein of Xaos. Some in pure javascript with openGL. That's fine but it's been done and I don't really want to go down that path; my focus is on movie generation, and creating a testbed for tinkering e.g. extensibility.
