I would think that interactive zooming would be quite nice ("illuminating") .... and for that 13 secs would not be tolerable.... Well... it's not at the top of my priority list ... ;-)
Sure, that comes under the 'fast enough' issue. But even Fortran might be too slow here? For zooming Mandelbrot I'd use PyOpenGL and a GLSL fragment shader (which would be a text string in Python): madelbrot_fragment_shader = """ uniform sampler1D tex; uniform vec2 center; uniform float scale; uniform int iter; void main() { vec2 z, c; c.x = 1.3333 * (gl_TexCoord[0].x - 0.5) * scale - center.x; c.y = (gl_TexCoord[0].y - 0.5) * scale - center.y; int i; z = c; for(i=0; i<iter; i++) { float x = (z.x * z.x - z.y * z.y) + c.x; float y = (z.y * z.x + z.x * z.y) + c.y; if((x * x + y * y)> 4.0) break; z.x = x; z.y = y; } gl_FragColor = texture1D(tex, (i == iter ? 0.0 : float(i)) / 100.0); } """ The rest is just boiler-plate OpenGL...
