Human powered Sand Printer

Back in the day, I elaborated and enhanced an idea for printing on beach sand by designing and having built a giant tow-able device. The concept business I called Cleaner Parks, as the message was always going to be a sponsored "Don't Litter" impression.

Today I came across a human powered sand printer using a similar technique (how many ways are there to print sand anyway?) but this one is a slower but more engaging method. 

This weird printer of a wheel made by Zanadesign, a Spanish design consultancy specialised in conceptual design –and of non organic materials so it doesn’t have impact to the beach and heavy enough to be used by a child but not pushed by the wind- is actually being used to spread the message of the commemoration of the first constitution of Spain in 1812 proof of peace, freedom and democracy.
