“Parents of the world, unite! You have nothing to lose but your plastic crap and credit card bills!” as Marx might, I suppose, have said, had he lived in the time of Toys R Us and the Tweenies.

I hadn’t even seen part 2 of Caine’s Arcade when I posted the first video about Caine on Friday. But then Alison pointed it out, saying she’d found it after crying over the Part 1 video that I’d embedded so I went to seek it out and… well… my eyes may have moistened a little.

I’m taking that as a sign that spring and hay fever are finally on their way and not as evidence that I cry at everything since becoming a mother, a bloody car commercial can set me off these days (why do they always have to bring in the string section and the kids in their little car seats looking all small and sweet and OH GOD they’re going to grow up so fast and become vile and after that probably move to the other side of the Earth and forget to even send their loving parents Christmas cards.)

Anyway. Alison was right. This one IS amazing and not just because Jack Black is in it. It’s the grainy home video of all the other kids around the world. Their goofy, gappy-toothed pride as they grin over their wonky cardboard creations, inspired by Caine.

So whether Marx is actually spinning in his leafy Highgate grave over the Tweenies or not, I’m saying it to you now: comrades, parents, carers… lend me your ears (bit Julius Caesar, I know, but since we’re plagarising)

Let’s throw down our plastic shackles (even if you only want to do it for the day) and join the cardboard revolution. The second Global Cardboard Challenge is happening on October 5 this year. Last year, there were over 270 events in 41 countries celebrating children’s creativity and the spirit of community.

Our community might be based around IP addresses rather than postcodes, but so what? It’s still pretty strong. Let’s do something.

Maybe we can get together in ‘real life’ and build a massive cardboard city with all our kids. Or maybe we can plot a way to join our efforts together online. We’ve got plenty of time to think about it. But put the date in your diary. Drop me a line with suggestions or some signal of general enthusiasm. And I’ll plot something around everyone’s availability.

VIVA LA CARDBOARD REVOLUTION!
