Harringay's Name up in Smoke

Coming home this evening, I walked through Trafalgar Sqaure and came across the Memory Cloud instalation.

Kinda fun - lots of smoke machines - you text any message you like to a given number and your message is projected into the smoke.

I couldn't resist and texted "Hello Harringay Online" Hello Harringay made it into the smoke. I tried but failed to effectively capture it on my phone video. You can see my awful efforts here. Hello Harringay comes right at the end - but it's of focucs (You can hear a girl neraby reading it out if you turn up the volume...........WOW!)
