Bianca Chang is an Australian based paper artist who creates these amazingly intricate 3D paper letter sculptures. I love incredible detail to them and that they are all cut by hand.
Her website has a video (below) that shows you the process, pretty cool me thinks.
And in case you are at this point going - dude she uses a lot of paper, well you'de be right. But its all 100% recycled and Chang says that she chose photocopy paper as it
"has an archival lifespan of 200 years yet it is treated as a highly disposable material - printed on then thrown away. I craft my sculptures from layers of 80gsm photocopy paper with the intention of transforming a typically consumable medium into a long term piece of art."
A simple idea, beautifully executed.
