Thomas Romer of the excellent Chop Shop Studio in collaboration with the nonprofit Planetary Society designed these delightful solar system toy blocks to teach kids (and adults) about the wonders of outer space! He's launched a Kickstarter to fund the manufacturing of the wood blocks with debossed typography. They're $75/set. Thomas says:
We worked on the project for over a year and while I did the graphics, etc — they made sure all the data was accurate and totally up to date. It is a set of 20 blocks featuring the most interesting worlds of the Solar System. Notice I didn't say "planets". One of my main objectives is to show children (and adults) that planet or not doesn't matter. There are worlds like Io and Europa that most have never heard of. Two moons are bigger than Mercury, never mind Pluto (also included).
Then each side is loaded with data like size, distance, interior, name, appearance and the missions we have sent to explore them.
When they are shipped to our (Kickstarter) backers they will be sold in the Planetary Society store and profits will be sent to support their overall mission.
