# Sleigh

> Tinsel pack asset: Santa's sleigh in glossy lacquer with gold scrollwork, curling gold runners, a cushioned seat and a sack of gifts in the back. It glides over a bumpy field, riding up each rise and nosing down the far side while the sack jostles behind. Raymarched in WebGL with a real ground shadow. Six palettes or your own colors.
