Adding to the ever-expanding list of things you can do with your cell phone, a Boulder-based startup called mShopper recently debuted a mobile shopping platform that combines the visual and tactile pleasure of brick and mortar shopping with the efficiency and cost- effectiveness of online shopping. Using mShopper's free service, consumers can easily compare the price of an item they'd like to buy from anywhere they get cell phone reception, and if they find that the price is right, make the purchase.

Say you're in a store drooling over a hi-def flat screen television but wondering if there is a better price elsewhere. Simply enter the first two letters of a brand and model to find out. For example, the search query for a Panasonic HDTV could be "pan" and "hdt", with the option to add more specific product numbers or information.

At present mShopper has more than seven million products in its database and adds countless more each month. The smooth and simple interface was designed from the ground up for simplicity and mobility, and is certain to revolutionize the shopping experience for the Blackberry, Treo and iPhone-wielding masses.

To try it for yourself, point your phone's web browser to shop.mshopper.com.

On the harbour in Vuurplaat, Rotterdam, a proposed Urban Cactus rises from the usually boxy Dutch architectural landscape. Responding to the natural setting of being on the harbour, UCX Architects envisage a housing project that is green with stacked undulating floor plates, giving large outdoor terraces to each apartment and allowing for light penetration. Details of eco-attributes have yet to be released but a cactus starting point could be a good sign.

Refinery29, our favorite co-conspirators in fashion, today launched Countdown, their series of online videos visiting top designers in their studios in the days leading up to New York's upcoming fashion week. The inaugural episode takes a look at duo Vena Cava who were recently nominated for the CFDA/Vogue fashion award, sneaking a peak at their upcoming collection and design process. With Alexander Wang, Rag & Bone, Jeremy Laing, Karen Walker and a wrap-up featuring footage from their shows coming up—all set to a swoon-worthy soundtrack—we're excited to tune-in over the next few weeks.

Part tack and part magnet, these office essentials designed by Hironao Tsuboi are capable of holding heavy-ish objects two different ways. The small, gold plated head is a double magnet so when objects are attached magnetically they appear to float (see images). When spearing notes into the wall, the thicker head also makes it easier to pry the tack out. Smart, bi-functional and sublimely simple, purchase them at 100% for ¥1,050.
