However, sorting by part can be frustrating. Imagine only 1x1 tiles/plates (i.e. the pieces which are 1/3 the height of a regular brick), to my knowledge there are:
* 1x1 square plates (i.e. with a stud on top), * 1x1 circular plates, * 1x1 circular plates, with a hole running through, * 1x1 square tiles (i.e. with a flat top), * 1x1 circular tiles, * 1x1 arch-shaped tiles, * 1x1 quarter-circle tiles, * 1x1 circular tiles with a nubbin on top
