A hinged dissection is a sort of geometric dissection where the individual parts are hinged together amd rearrangement of the parts can change the appearance of the object.
The following hinged dissections are generated by simplifying two target shapes into pixelated enitities and figuring out a way to transform between them. The design process can be described by the following steps:
Sword and Shield
In this particular case, the shield is folded in half before initiating the transformation.
This table can transform between an equilateral triangle and a square. The dissection is a variation of Dudeney's dissection and is based on the work of Greg Frederickson .
 Designing a table both swinging and stable.
