A wonderful little video about the power of progressive tinkering to solve increasingly more challenging problems. A Lego car is re-engineered to cross ever-larger gaps, and it’s compulsive viewing. There’s also another one about climbing over a growing pile of books.

Many years ago I wrote a column about Lego the company, which ended up being quoted in a book on creativity. The Danish toymaker had a fascinating ride back to profitability, partly by letting tinkerers freely invent what to build next with its bricks. There’s clearly no end in sight.
