Vivien Muller (previously) has created a new “plant,” Orkys. This one uses flexible photovoltaics as leaves to light what appears to be LEDs in in the flowers.
I prefer his previous work, PhotonSynthese more though. Aesthetically, it’s more pleasing with the brushed metal stems and the blue leaves, instead of the all black stem and leaves. However, the more flexible materials in Orkys makes it easier to introduce nitnol wires in the leaves for sun tracking. Also, PhotonSynthese does something, while Orkys just sits there and looks pretty. There’s no reason why you can’t have something like this do both.
