What would you say if I told you that this "sea sponge" lamp was actually made from... wait for... masking tape?! It's true!
This delicate-looking lamp, reminiscent of underwater organisms, is made from dozens (hundreds?) of pieces of rolled-up tape. It's pretty brilliant, honestly. My only concern would be the inevitable dust factor. Maybe you could spray it with some kind of varnish or clear coat?

*The word of the day is 'sponge' in case you were wondering.
