Commuters at London's Waterloo Station may have noticed a change in proceedings this week, as the location became home to a huge petri-dish, which hosts thousands of fast-growing yet harmless bacteria, appearing ahead of the launch of apocalyptic drama 12 Monkeys.
Inspired by the 1995 movie of the same name, the television series stars Aaron Stanford as time-travelling Cole, who utilises an untested and dangerous method of time travel to travel to the present day from a decimated future in 2043.
Hoping to save the human race from a deadly plague, he'll be joined by co-stars Amanda Schull, Kirk Acevedo, Barbara Sukowa and Noah Bean.
Appearing overnight on Sunday, travellers have been bemused trudging back to work following the half-term break, and over the course of the past two days, colourful bacteria have begin to take shape in the dish, piquing the interest of hundreds.
Beginning to emerge is a sympol comprised of fungi, slime and bacteria, all with varying speeds of development and playing into the theme of the series' fictional fast-spreading "kalavirus".
As a literally 'viral' marketing stunt, it's the first of its kind in Europe and eventually, will show the red colouring and texture of the 12 Monkeys logo.
12 Monkeys premieres on Syfy this coming Friday at 9pm.
