I saw a program recently on the telly suggesting that we should build self replicating nano robots to explore the universe. The idea behind seems to be that we will imitate successful viruses etc and also get a better 'weight'/efficiency-ratio when it comes to acceleration etc. But self-replicating?
Lets see... 1 2 4 8 16 32 64 128 256 512 1024 2048 4086 .... That number will rise very fast, it seems to me, as long as there is sufficient 'raw materials'.

They're commonly known as von-Neumann machines and have turned up lots of sci-fi literature.

Have a look at:

...And its claws are as big as cups, and for some reason it's got a tremendous fear of stamps! And Mrs Doyle was telling me it's got magnets on its tail, so if you're made out of metal it can attach itself to you! And instead of a mouth it's got four arses!

'self replicating nano robots to explore the universe' - I think somebody put Absynth on their cornflakes instead of milk.
