The paint roller doesn't paint anything on the wall. It's made with green LEDs. A camera next to the projector tracks the position of the paint roller, unmasking the video projection in real time, as the artists draws on the wall. Pretty clever.

From afar, the scene is a little more grim (click for larger version):

And seeing it up close makes me wish for a full-length menu bar:
Still though, if you need to indulge your fanboyism, please, do it like this. —Thanks, Tristan!

Sure, fire tagging is relatively dangerous, what with a school in LA having been partially burned down from the practice, but as long as you're smart enough to not try it on the side of an old wooden barn it shouldn't be that bad. And some people are tagging with lighter fluid, making it less permanent than regular graffiti. Lighting wet paint on fire makes it permanent, but with burned accents, which is cool too. But something about making graffiti more of a performance and something to be witnessed right after it's done is especially pleasing to me.

Unless it was on the side of my convenience store, in which case I'd call the cops on those no-good punks. [Gothamist via Fast Company; Photo by Faith-Ann Young]

The toy itself doesn't require a Wii to work: It uses Flash on a normal PC as the platform, and the Wiimote as the controller. However, I wish Nintendo and its developers could look at this and be more creative about the use of the Wiimote. Even while this will require a big screen, I think kids will love to paint like this on their TVs, while parents will be happy for them not use spray or crayons over real walls. [CLDFX]

Seriously. Short of the DJ/rave scene these cans might have trouble finding a home. The price isn't too bad at $80 for the Tank model, $50 for the Matador, but I go blind just thinking about them. The Tank includes an extra cable with a microphone for answering calls, so there's that to consider on your way to that abandoned meat packing warehouse on the city limits.

The looks you'll get because you're wearing these for attention are priceless, however. [Aerial7 via Chip Chick via Coolest Gadgets]

You can download HWPen today using Installer.app. Go to "Sources," click on "Edit" and "Add" a new source:

Then refresh your sources and look for HWPen in the iPhoneCake packages category. Install the software and restart the iPhone.

You will have to restart your iPhone.

The software is still in beta and it has quite a few errors—it doesn't work correctly in landscape mode and it doesn't appear in Mail.app for now—but it works a bit better than Doonesbury's original Newton (I just started using it, though), although not as good as later incarnations of the Newton or Graffiti, as you can see in the video. But it's a start and hopefully it will get into a solid alternative for the people who hate the on-screen keyboard (I prefer the keyboard myself, it's just a lot faster than I would ever be doing character recognition).

Yuri Suzuki's design uses a Post-It pad to mark out the frequencies of pirate radio stations that caught her ear while living in North London. "My radio enables you to make notes about the radio station and mark its position," she says. "The radio looks like a memo pad, but underneath is a speaker; the pencil acts as the antenna that controls tuning and volume."

Yuri feels there is a connection between graffiti artists and pirate radio stations, as both are art forms that hack into public spaces. Her Future Pirate Radio lets you tune into pirate radio via QR codes. First, the graffiti artist stencils a QR code onto the wall, incorporating it into their work. Anyone who takes a picture of the graffiti will then be able to tune into the pirate radio station that inspired the artist via the internet.

Finally, Jochem Faudet's work consists of a pair of radios whose controls are grouped together in order to make it easier to use. Actually, it's rather complicated, so here's Jochem's own explanation.
"Radio 1: All the tuning and volume functions are grouped around the speaker. The On/Off switch and volume function is situated closest to the speaker. The AM/FM switch is situated at the end of the tuning circle, by flicking the switch down it points to the FM numbers situated on the outside of the circle or by flicking the switch up it points to AM numbers on the inside of the tuning semi-circle.

"Radio 2: The tuning function and volume function are separated from each other in this concept. To adjust the volume one has to turn the wheel with the integrated speaker, by sliding the AM/FM switch to FM it hides the frequencies of the AM and vice versa."

Nope, still too complicated for me, I'm afraid. [Dezeen]

Not sure when or even if this will come out (and it looks like it'll be in Germany) — but it's a godsend for tech-savvy gang members. By the way, if you're not sure what a "citylight" is — it's that large, vertical LCD screen that you see in the picture. [Ads of the World]

The L.A.S.E.R.TAG tracks the motion of the green laser through the camera and then projects the 'ink' onto any large flat surface—like in this case, the side of a large building.

The lab has instructions on how to get started with creating your own tagging projector, and they've thankfully released the source code to help you on your way. But remember, even if you get one successfully built, you still need some art skills to properly do graffiti. – Alexander Yoon

This devious robot is the latest from the activist group Institute for Applied Autonomy, and comes complete with this bogus stat:

"Studies have shown that in nearly 100% of the cases, a given agent of the public will willing participate in high profile acts of vandalism, given the opportunity to do so via mediated tele-robotic technology."
