Muse this week features films posters, books covers, Photoshop art and derelict trains – and a Photoshop tutorial. Even a cute Panda bear. As always, any ideas or thoughts, send them in! Thank you to those who contributed this week.

Who hasn’t built sand castles? Harrison Hot Springs, BC, Canada, hosts the World Championship of Sand Sculpture – with some amazingly detailed (and very large) sculpture, made entirely from sand.

Pixellica is published from a Macintosh laptop (somewhat like a portable office) – over the years I’ve been using a Mac, I’ve had several Apple-themed wallpapers. Granted, tracking them all down again was time consuming (and ones I couldn’t find I’ve uploaded on Pixellica), but here’re 15 of the best Apple wallpapers to dress up your Mac. Or PC.

Street acts are as varied as the people that perform them – Three Card Monte, Juggling, Singing (even hawking cheap Rolexes if that’s your thing). These performers take their art very seriously and dedicate hours to locking their knees and elbows and not moving – or at least moving a claymation-style stop and start fashion. Some are very realistic.

Swedish-based photographer & digital manipulator Erik Johansson cites painters Dali, Magritte, as well as Escher and Rob Gonsalves as his sources of inspiration, and the inspiration is evident. However Erik puts his own unique angle on abstract art – and accomplishes it seamlessly. Erik pulls it off so perfectly, the only thing standing in the way of their believability is common sense.

When I was little, I played with Legos – I had (well, still have) Legos from the Space, Castle, Train, Pirate and even Technic branches. The sets never lasted in original form and always morphed into elaborate projects of my own. But Andrew Lipson and Nathan Sawaya take building with Legos to a whole new level.

Expression rears its head in so many forms it’s impossible to count – but most often, it’s in some form we can keep, or at least that’s publicly appreciable. Ice sculpture melts within a few hours but is eye-catching and sparkly; sidewalk art from the likes of Julian Beever just washes away with the next rain but can be loved by throngs of people who walk by. Scott Wade has neither of these luxuries.

Pixellica begins publishing a new feature today: Muse. Muse is a weekly collective of inspiration and often-overlooked creative pieces that otherwise would probably not make it into a full-blown post on the site. Muse will feature anything creative or inspirational: motion, photography, painting, digital art, illustration… what strikes the creative fancy. If you have any link that inspires your muse, please send it in and keep the weekly feature interesting!

Sometimes we work so hard to produce something colourful and graceful in Photoshop. The marvelous creation around us does it naturally – and unwittingly. Jelly Fish are a prime example of “look but don’t touch” and Pixellica presents a collection of 15 examples that highlight the grace and colour of these untouchable beauties.
