In this paper I focus on the concept of diagrams, as they have been appropriated from a Deleuzean discourse into the philosophy of Manuel DeLanda. For strategical reasons Gilles Deleuze reiterated on several occasions a caution against subjecting diagrams to history. Yet, this is exactly what DeLanda seems to invite us to do. To counter this tendency, without abandoning DeLanda's perspective, a new passage between the virtual plane of consistency and concrete machines is invented. This paper is not a final solution, but an elaborated strategy which points ahead towards intensified efforts in investigating the evolution of visual screens.
