       | The Thomas attractor reminds me of the ship in the film

       | Wonderful. Differential equations were my favorite subject in
       | school. Unfortunately the chaos theory class was only offered
       | every other spring and I missed out on it.
       | 
       | As a heads up: the "Preset" button label seems to be a typo -- it
       | appears to "Reset" the animation.
       | 
       | A way to copy the parameters would be nice (even just allowing
       | text highlight).
       | 
       | Cheers.
       | 
       | PS -- I stumbled across a very nice Thomas solution {b: 0.2, x_0
       | = 1.1, y_0 = 1.1, z_0 = -0.01}

       | I've seen (though can't find immediately again right now)
       | animations based on rotating through interesting parameter sets
       | for some of these systems, rather than animating the progression
       | through one parameter variation as seen on these analyses, which
       | was rather mesmerising too (not dissimilar to the ifs module I
       | remember from xscreensaver in the late 90s).

       | Wonderful vizualization and library! Many years ago I made a
       | Chua's circuit PCB for an electronics course[0]. We had to dust
       | off an old Cold War era analog oscilloscope to actually see the
       | attractors because the resolution of the newer digital ones
       | induced too many artefacts.
       | 
       | I want to use this library to vizualize this using the electronic
       | component values now.
