This took me a while, but I'm quite pleased with it!
It is a periodic table of QR codes, with each code linking to our YouTube video about that element.
If you don't know what a QR code is here's a Wiki article.
And here's a link to a hi-res version of the poster... Feel free to print it out and stick it up somewhere for us!!!
And here's a link to a version with symbols under each code...
PS: Special shout-out to Professor Merrifield from Sixty Symbols who loves QR codes much more than me and will be rather smug about the fact I've done this!
