looks cool. I don't know viewmat or mandelbrot formula well, but a pair of
rationals might work.
a fairly insignificant criticism is
mbrowse_z_ =: conew & 'mbrowse'
is more robustly,
mbrowse_z_ =: conew bond 'mbrowse'

Subject: [Jprogramming] feedback wanted for mandelbrowse tutorial
Hey all. Happy new year!
I made a small GUI app for a tutorial video I'm planning:
https://github.com/tangentstorm/mandelbrowse
It draws the mandelbrot set, and lets you zoom in and out.
I was hoping I could get some feedback on the code before I filmed anything.
In particular, you can only zoom in a few steps before the edge starts
smoothing out.
I think the problem has to do with lack of precision in J's complex number
type.
Is there anything I can do about this, other than implementing my own
complex
number type as a pair of extended precision numbers?
Thanks!
-Michal
