Abstract. We report here the design and implementation in vivo of a gene circuits that can be used to count to 4. In essence, it uses two toggle switches, each storing 1 bit, to keep track of the 4 states. The design of the counter is highly modular, in the hope that it can be included as a unit in larger circuits, but also combined with similar units to keep track of a much higher number of states, up to ((n+1)^2) with n units.

- design: modularity (use two interfaces) - propreties -> stable? - availability in form of biobricks
