As part of its Street Summer season of programming and events, Channel 4 has created an iPhone app called Street Tag that allows users to virtually graff any wall or surface they fancy using their iPhones...

Essentially, the app is an augmented reality toy which turns your phone into a can of virtual spray paint. "Using the phones camera mode, it lets you graffiti the streets in real time," explains Alice Tonge of 4Creative who worked on the app. "You can adorn everything and anything, even those buildings you never thought possible, and not get arrested for it. Plus you can geo-tag it so others can see your work."

We've had a go with the app and its ability to recognise walls - and let the virtual paint sit flat on them - is really  impressive. It's a shame our graff skills are far too lame to be able to share with you.

The app is free and available via iTunes

There's also a very nicely crafted TV spot (written by 4Creative) for Channel 4's Street Summer season which features graff artist Artful Dodger, cyclist Danny Mackaskill, and a host of musicians and MCs including Professor Green, Ms Dynamite, Faith SFX and more...
