Yes!
From the astronomy open house at UH.
Lily got all hand's on and made some astronomical stuffs.
They had lots of activities. One of which was a do it yourself pin toy like these:
where you put in the pins into a black box to find what type of terrain is below. SUpposed to model remote sensing of terrain on Mars or Venus.
With the low res version, there's only 40 or so pins (8 x 5 grid), mid-res about 80 and the high res is something like 150 you get the correct "map" created.
The people who brought it had considered not even bringing the hi-res one - figured no kids would actually have the patience to do the whole thing at each of the three resolutions
Turns out there were two who did.
