An awesome and easy idea: A "lampshade" with removable motives and the possibility to design these by yourself.
The lamp was reduced to the essential, consisting of a support, a lampshade (with the shape of a flat square Plexiglas) and a clamp.
The motives are (mostly) transparent image foils that you will get in brilliant quality or order according to your own proposed picture. However, this also works fast and easy in a copy shop or with a good printer.
