Symmetry is an age-old device of the visual artist. The word refers to two halves that perfectly mirror each other. In design, symmetry is closely tied to balance. A perfectly symmetrical design achieves balance and a sense of stability.

There is also asymmetrical design, where the two halves are balanced but do not mirror each other perfectly. The majority of websites have an asymmetrical layout.

Most often we find the logo in the top left, balanced by some navigational elements on the right. In the body, the side columns are usually balanced by either the main content or other columns.

While perfect symmetry is certainly not new to the web, it is gaining momentum. Expanding screen sizes and the proliferation of platforms and viewing options are making it a more attractive option. By mirroring the halves of a design, you not only get a greater sense of balance, but also improve the flow from top to bottom.

Every week we tweet a lot of interesting stuff highlighting great content that we find on the web that can be of interest to web designers.

The best way to keep track of our tweets is simply to follow us on Twitter, however, in case you missed some here’s a quick and useful compilation of the best tweets that we sent out this past week.

Note that this is only a very small selection of the links that we tweeted about, so don’t miss out.

Erin Mulvehill is a young photographer based in Brooklyn, who graduated with a BS honors degree in photography from Syracuse University.

Unlike many modern photographers, she shoots on analog 35mm film (she scans the negatives to do post-processing in Photoshop).

In this post you’ll see the breath-taking photos captured in her Underwater, to be reborn series, which has been dedicated to the waters of the Gulf of Mexico.

The Underwater series includes images of what resembles girls trapped under ice, frozen in time. The photos are chilling and hauntingly beautiful.

There are twenty four images in the series, with at least a dozen different models. The idea for the series, according to Erin, came to her in a dream. And despite appearances, the photos were shot in a studio, not underwater.

Some people collect stamps, others spot trains; I have become obsessed with wireframing software.

I have tried and fallen in love with countless applications, from Balsamiq to Mockingbird to FlairBuilder. Although each has felt like true love, over time my gaze has wandered, and I find myself flirting with another tool.

They all look so alluring, but over time I see their shortcomings. Perhaps I am just too fussy. Perhaps my needs are too unusual. What I really want is a tool that fits the way I do things, rather than me having to fit the tool.

Do you have a favorite wireframing tool of your own? Do you even see the need for one? If so, do you go for all the bells and whistles or just a quick and dirty solution?
