Rectangular tiling, random pattern

Hi all,

I just wanted to share with you my first hoopsnake test. My idea was to create a pattern growing randomly without leaving gaps, using simple 1x2 size tiles to cover an underlaying grid.

First I had some trouble setting the definition up, having to use 3 nested hoopsnake components, but then i found a way to simplify it down to using just one component.

I think it could be simplified down a bit further, as I now check for each grid-unit's neighbour in all 4 directions, however in reality i only need to know wich number is to the right and above.

I added a picture of the definition in action and an illustration to try to explain how i thought when i set up the rules.

Just rightclick Hoopsnake and loop to start the growth. Enjoy!
