Dutch designer Bob de Graaf has developed two clever solar-powered lamps that act like autonomous creatures and respond to our movements. 

De Graaf's ‘Species of Illumination’ are built using sensors, so that they can react to movements, or detect the darker parts of a room to light up.

The illuminating pets each play different roles and have been given nicknames:

“Wallace” responds to changes in light intensity in its environment and brings light to dark corners.

“Darwin” spends daytime hours searching for sunlight to charge its batteries so that it can follow around its ‘owner’ at night, providing them with light.

According to De Graaf, the movement and interaction with the creatures can trigger an emotional relationship, which he believes can contribute to a person’s wellbeing.
