Probably the carob powder my health-kick parents had us put in our milk instead of chocolate.

Giant snails are the cause of the white trails on Sputnik Planum :

So I'm pouring wax blocks this morning for a project and something recognizable came about as it was cooling.

This is the most analogous substance I've seen to compare Sputnik Planum. Of course, the action occuring here is convection from the very hot wax on the bottom floating up to the top and cooling down once it reaches the much colder surface-air medium. What is most interesting I think is that for the wax to have this appearnace with the much darker regions, there has to be liquid present under the solid layer, otherwise, it all has the homogenous appearance of a cool wax block. On sputnik Planum, many similar areas of darker and lighter regions exist as well.

Advanced image processing techniques pioneered by the people behind CSI and CSI: Bognor Regis were applied to New Horizons images of Triton --- with spectacular results!

Have you tried to work out the reynolds number of the wax?

Just came across this painting, "Floating city" from 1981, by Sci-Fi artist David A. Hardy.

Seems he had access to NH imagery a good deal earlier than anyone else! :-0

In the 'other stuff' category we got this presentation for a possible mission to Pluto.

PDF with a powerpoint style presentation of the mission concept.

Did the FRC fusion technique make significant progress since this paper of 2012?

The fusion reactor seems to be the bottle neck of the mission design.

That's got to be the funniest thing I've heard all week.

It's only 20 years away... and has been for the last 50. Though to be fair, an engine to burn a limited amount of fuel is is probably not as difficult as actually building a facility that self-sustains itself and produces more energy than it takes in (though we can still dream!)
