What would it be like, if you could change your lamp shade quite often and any time you wished to? Have a look at this A4 Lamp which allows you to have a shade of your choice whenever you want. The lamp basically is a laser cut sheet of stainless steel which comes flat packed. The stainless sheet is to be folded as directed to obtain a particular structure [shown below].

After fixing the bulb in the circular portion of the stainless steel structure, you just need to get hold of an A4 size paper [with any print on it] to clip it on the stand for an instant lamp shade! The A4 Lamp has been designed by Inon with Boaz Mendel.
