Just you try and get your olds to guess 20 internet things from last year. They might be able to take a stab in the dark and conjure up images of Rebecca Black harping on about Friday, but let's test your knowledge with Syzygy's annual sketch of the internet-nerd's calendar (see 2010's here.)

The latest sketch has been crafted by Peter Jaworowski, who is offering up a signed limited edition print if you tweet about the illustration using the hashtag #20things. Yes, it's a shameless PR ploy for the design and marketing group Syzygy, but I don't mind being used as a puppet when their dance is just so much fun.

And frustrating! I must admit, I'm kind of stumped with some of them. I can see the Anonymous masks; the LulzSec mascot; Google+ logo; Nyan Cat and maaaaybe Obama's turkeys, but probably have to hand in my Internet Nerd badge for not getting the rest. Can you do any better? [Syzygy]
