karika by gyöngyi bokor from hungary
designer's own words:
Ka-ri-ka is a solar powered light.
Its simple torus form gives many opportunities of use.
In one case the light can be framed into a suction-cup which is fixed to the glass of the window.
In an other variation ka-ri-ka can be attached to the framework of a chandelier. In both case any of these lights can be replaced from the window, and can be taken anywhere in the flat.
