A quick break from any serious posts 🙂

First a LEGO bridge that I put together, held up by the tension in the inverted catenary suspension ‘rope’.  It’s surprisingly sturdy – it can be picked up and moved without danger of breaking – the tension gives it quite a bit of strength.

And next a tower.

I starting running out of LEGO and so had to resort to balancing it on LEGO trees.

I made this after fiddling with the blocks and realising that I can quite significantly increase the sturdiness of a tower by forcing the LEGO blocks to connect an angle to make a trapezoid shape.  I played about with different shapes and angles to maximize strength.  The result looks very slapdash, but it’s surprisingly strong.
