You go to a museum in 2009, and you can see the remains of past civilisations. The Minoans. Carthaginians. Romans. But as their time came to an end, so too will ours.
Where their remains tend to be coins, or fragments of pottery, ours will probably look a little different. A little something like this.
These "modern fossils" are by Christopher Lambert, and if fake historical (well... palaeontology) relics are your thing, they're available to purchase.
