Also known as "MindCrack" for its ability to mesmerize boys from the ages of 2 to 92 who have ever loved Legos, Lincoln Logs, Erector Sets, Meccano, and the plethora of other hand-eye-coordination-building toys that enable future engineers, scientists, and others of a technical bent to get their groove on as Makers-to-Be. I had a bunch of 11 - 13 year-old boys in 6th - 8th grade physical science classes who asked if they could build a required diorama of the nitrogen, carbon, and water cycles in MindCrack as the girls had already grabbed all of the paper, cardboard, glue, paint, etc.
I thought I had them when I said, "Yeah, but you have to annotate each of the steps with text.", to which they simply pointed out the carved wood lettering, and I had to admit they had _me_ there. I couldn't believe what they built in a double-block class period - all three cycles, fully labeled with Yogi the Bear style Jellystone Park signs, with a waterfall coming out of a cloud for rain, a river leading to a shore of a lake, waterfalls going _up_ into clouds over the lake representing evaporation, etc. I still haven't figured out how they did that - it may have been done with an add-on, and the ones that provide fire, electricity and other forms of energy are just mind-blowing
The value of the Python API cannot be underestimated - showing budding pyromaniacs (aka most boys and a few girls) in the classes how you can build a 10 by 10 by 10 stack of TNT blocks in a millisecond in three nested code loops is "a technology sufficiently advanced as to be indistinguishable from magic", as Arthur C. Clarke sagely observed. Giving dibs to the student who hits the massive block with the sword as everyone stares, open-mouthed, while the screen fills with fire, smoke, debris, etc., to reveal, a solid minute later after the smoke clears and the dust settles, a crater seemingly half the size of the world, rimmed with vegetation with shredded leaves, is one of those rare moments when an educator has otherwise bored, disengaged kids eating out of the palm of their hand. When you show them how to detect when another player gets too close and then teleporting yourself a safe distance away that isn't over a cliff ... well, let the games begin!

The best things in life aren't things ... but, a Pi comes pretty darned close!
