It is simply staggering how complicated some items really are. We never think about it, but some items that we use every day consist of hundreds of parts meticulously put together and working perfectly. Todd McLellan is a photographer who based his newest book “Things Come Apart” on the complexity of various old and new tech. By carefully taking apart various items and arranging all of the parts in perfect order, Todd has allowed us not only to look inside various appliances, but also to appreciate the astounding complexity of these items. Just like the human mind, we are so used to seeing and talking with people that we forget just how complicated their minds really are. It would be great if we could “take apart” the human mind in order to gain some insight into the person’s thoughts and desires.

Chris Gilmour is one of those people that can turn unexpected things, which most of us would simply discard as trash, into astounding works of art.

His cardboard sculptures include everything from vehicles (motorbikes, cars, bicycles) to religious symbols.
