The first green dream is the “Green Light”. A plant (Hedera) grows around an (energy saving!) lamp. You can grow it or cut it to dim or brighten the light. Coming soon in alternative versions such as Woodbine (Lonicera), grape, and tomato plant! Designed by Twan Verdonck for DreamingreeN. Available in the shop in three formats: product, DIY and download.
Odd, I can’t find the DIY plans, but it’s pretty easy to re-make this.
