I am a huge fan of Gelaskins, and my iPhone has boasted one since I discovered a display at a small Toronto store back in May. Adhesive art for your iPhone, iPod, and Mac is a fantastic concept and a great way to express yourself beyond the typical hardware case.

Infectious is another site that offers art for laptops, cars, and more. They have recently launched a line for the iPhone. The site currently has 38 different pieces of art for the iPhone, and is currently on sale for $9.99. The Infectious stickers will fit both generations of iPhones.

You will get a large piece of art for the back of the phone, and a smaller one for the front that goes over the Home button. The artwork for the front of the iPhone is a fantastic feature that Gelaskins doesn't have, and one that I find very attractive. It makes it easy to spot your phone without having to flip it over to check the back or activate the screen to check the wallpaper.

Art for laptops is starts at $29.99 and will fit the Powerbook G4, iBook, MacBook, MacBook Pro and MacBook Air. The artwork is made on 3M vinyl material and can be easily removed to put on another piece.

Infectious is currently offering a deal for TUAW readers. Use discount code TuawRocks for 10% off from now until December 31.

A massive spectacle is brewing in Canada. From the 4th of October through the 12th, the two towers of Toronto's city hall will become grandiose pixel displays with the help of Project Blinkenlights. Dubbed "Stereoscope," the installation will use wirelessly-controlled lights placed behind the windows of the building to generate the pixel art. This project adds to the growing list of large-scale interactive light installations executed by Project Blinkenlights... it also happens to be as Mac-friendly as they come, thanks to some help from our friends at The Coding Monkeys.

When we talked to Martin and Dominik at WWDC, they hinted at their involvement in this project. They stayed pretty tight-lipped about it, stating only that it would be "big." Now they've unveiled a simulator for Leopard and a mobile version for the iPhone [iTunes link] which allow users around the world to watch in realtime as the exhibition unfolds. Beyond that, they had a hand in creating some of the tools which allow users from all over the globe to generate and contribute their own animations for the event.

I've been playing with both the desktop and iPhone simulators, and I'm duly impressed. The iPhone version -- with smooth, touch-based navigation and amazing 3D rendering -- is definitely not to be missed (especially since it's free). This event would be big enough if it stayed in Toronto, but Project Blinkenlights and The Coding Monkeys have made it possible for users around the world to take part in the spectacle. Check out the gallery for more shots of the iPhone version of the simulator in action.

Tate Liverpool, one of the Tate art galleries scattered around the UK (the two main galleries are in London, another is in St Ives) has opened an experimental online exhibition tour for iPhone and iPod Touch owners, which it says is the first of its kind in the country.

From now until the end of August, visitors to the Gustav Klimt exhibition will be able to browse the free guide content to their iPhones over the gallery's wifi network, or download it beforehand as a podcast. Spare iPod touches with the content pre-loaded will be available for hire for just $6 (£3).

According to an article about the experiment in Design Week magazine, the guide has been very popular and upped average visit times from 45 minutes to three hours.

If you want to try the tour for yourself without making the trip to Liverpool, you can enjoy it in full on the web.

Thanks to Jonathan for the tip.

Satta van Daal is a talented stencil artist from Germany, now living in Australia. His canvas? A vast array of old Macs: from SEs to LCs to PowerBook 100s. He decorates them with everything from vignettes of Steve and Woz to carefully recreating the look of Susan Kare's original one-bit Mac icon set.

If you live in southeast Australia, and have an old Mac you're willing to let go of, he might turn it into his next work of art.

He plans on showing his art in an expo titled iPaint MyMac later this year in Melbourne, and hopefully Sydney soon after. You may like his t-shirts, too.
