I have enough Geomag[1] to make 2 icosahedra[2] drons whatever
I have an assortment of colours
Last night I fiddled about splitting the colours evenly between the two, and then trying to find pleasing arrangements for them.
On one, I found you can have 3 orthogonal opposite-ends-of-the-thing pairs of edges, and did that in 3 colours, filling all the gaps with the last colour (I have more red than I have green, blue, or white) It's OK, but it'd rock if I had 5 colours so could lose half the reds and get everything fully paired up. So I may need to return to Toys'r'us[3] soon.
On the other, I had a triangle of each of green, blue, white meeting at one face, with a similar arrangement at the opposite face, and the wiggly equator left over filled with red. That's quite pleasing.

Which would be better for saving energy - coating every available surface in your home with photovoltaic cells to recapture light from the bulbs and turn it into electricity again, or installing mirrors everywhere so you get the maximum possible use out of the photons?

But you (I'm pointing at you,
