Action Types is an experimental type project by German Designer Marcus Schaefer. It is a 3 dimensional alphabet which includes 3 different fonts that can be discovered by turning the letter blocks around. If you want to explore them by yourself, try the interactive version on his website.

The basic idea of the project was to create a typographic toy to show children different types of fonts

The 3 dimensional letters include three pretty different fonts – a bold, a light and a serif (slab serif) one.

Turning the Action Types base models, several random fonts can be constructed by interpolation of the basic fonts.
