[libreplanet-discuss] Libre-respecting CS or engineering toys for kids?

[Pen-Yuan Hsing]

Dear libreplanet,

I'm hoping to buy some toys as gifts for a couple kids aged between 
~3-5, and I'm hoping to get them (especially the little girls) 
interested in the STEM (science, technology, engineering, and math) 
subjects.

Can people recommended some freedom-respecting toys for this purpose? It 
doesn't even have to be something installed in a computer, for example 
CS Unplugged (http://csunplugged.org/books/) has a great book that 
teaches basic computer science principles.

Maybe we can then submit these ideas to the FSF's holiday gift 
recommendations list.

Thank you!
