honeycomb decay

Mathematica can save time delays between frames together with animated GIF (look for "DisplayDurations" under options of GIF format). This in turn allowed me to produce exactly 28 frames for the decay of this honeycomb with 28 cells. Modelling radioactive decay, where for example time intervals between clicks on a Geiger counter are approximately exponentially distributed, I can simulate the delays (rounded and shifted to run from t1/100-th seconds with average value (t1+t0)/100-th seconds) as:

delays[{t1_, t0_}, n_] :=
 t1 + Round[
   RandomVariate[ExponentialDistribution[1/t0], n]]

I set t1=2 here. Most browser can't present a delay of 2/100-th seconds properly. Chrome can.

Yes, this, temporarily overriding the equality criteria, if I understand it correctly.

This happens to me too (Win 8.1 x64, Mma 10.0.1.0). I think I've always switched keyboards so far. I'll try now not to.

Vectorize the image first to PDF for example via online.rapidresizer.com, then import that to Mma.

Bad trick #2: FrameTicks -> {Automatic, {{.5, "+\[VeryThinSpace]0.5"}}}.

This is hardly noticeable ... Could you put y-label on the right perhaps? FrameLabel -> {"x (Meter)", None, None, "y (Meter)"}
