This cartoon-like balancing "Sax on legs" is playing 'Trinkle Tinkle' (song by Thelonious Monk) and it is a funny design by Rikki Donachie.
The Sax On Legs is made from 3 parts, the sax itself is folded from half of A4 paper and the arms and legs from a fourth of A4 paper. It's not completely closed.
