In the broadest common definition, accelerator is a system capable of increasing efficiency of other systems. On of the ways to achieve acceleration in physical systems is ordering and rooting flows depending on their specification, segregating, buffering and upgrading each item it the system before realizing ordered flow into the main stream. Same systematics can be applied while dealing with urban flows, their quality and efficiency. Well located local system can considerably affect city animation positive factor in global scale. 

Presented design is both, public intervention for problematic and anesthetically urban plot in the centre of rapidly growing city and accelerator for flow an animation of surrounding  urban tissue.
