Industrial Designer Sabine Marcelis Upgrade's Ikea's Hot-Selling Lamp

The VARMBLIXT , Ikea's donut-shaped lamp, was designed three years ago by Rotterdam-based industrial designer Sabine Marcelis. Since then, it's been selling like hotcakes; the company says they sell one every five minutes.

Now the design's getting an upgrade, courtesy of Marcelis. The finish has been switched from glossy to matte, and instead of only coming in orange, she's added color variability: The lamp switches between twelve preset colours carefully curated by Sabine Marcelis.

The sequence moves through different temperatures of white light, into glowing amber and warm red, through soft pink, cool lavender and turquoise, and on to gentle yellow tones, before circling back to white light. Each colour is chosen to transition smoothly into the next, allowing the atmosphere to shift gradually to another, without disrupting the feeling of a room.

Rimowa and Vitra's Luggage-like Aluminum Stool

This unusual object is the Aluminum Stool , by Rimowa and Vitra. The German luggage manufacturer and the Swiss design furniture company collaborated to create just 1,000 of these; and while the overall look is pure Rimowa, the piece is meant to be storage furniture, not luggage.

"It is almost a typology of its own," says Christian Grosen, Vitra's Chief Design Officer. "While the cube format might not be so practical for a suitcase, it's ideal for sitting and storage." "During the design process, we decided to leave out the handles so that the stool wouldn't closely resemble a trolley or a transport container.

There is a seat cushion and the inside is also padded; we deliberately left the wheels, as they are emblematic of both furniture and suitcases. The Multiwheel system is a RIMOWA trademark, as are the grooves in the aluminium.

Design Criticism: Are These Transitions Good or Bad?

In design, the transitions between surfaces are everything. And in a perfect world, those surfaces are designed at the same time, giving the designer the luxury of thinking things through.

Sometimes, however, things need to be retrofit. And then it's up to someone who may not have any design training at all to come up with a coping solution.

What do you think of these four executions: 1 2 3 4 My opinions: 1. Way too busy, and distracts from the original molding, which is meant to be a design feature; downspouts are not.

A Vertical Wind Turbine for Sailboat Masts

The beauty of sailboats is that they don't require power in order to move. However, modern-day sailboats have a host of onboard electronics that do require power: Navigation lights, radar, a VHF radio, a GPS unit, the navigation console, interior lighting.

These are typically powered by batteries, which are charged by an auxiliary motor if the boat has one, or the boat can be plugged in at the dock. However, a Belgian startup called Phileole has invented an alternative: This Grain Blanc wind turbine.

This can be bolted to the mast. Because of its vertical orientation, it can capture wind from any direction.

A Stylish, More Functional Update to the Granny Cart

This Roulette Cart , by a Belgian company of the same name, is designed to make grocery shopping easier in urban environments. It was designed by Belgian industrial design firm Futurewave (though at press time it wasn't yet on their website).

It's sized for the city, at 64.5 cm H × 34 cm W × 24.5 cm D (25.4" x 13.4" x 9.6"). The frame is powder-coated aluminum, and the bag is waterproof nylon.

The skateboard-like wheels are made out of TPU. The bag has a 40L (10.6 gallon) capacity and features several interior pockets.

When Beautiful Design Crashes Into Reality

This beautiful Topos Chair and Sunlounger were designed by Zaha Hadid Architects. They're in production by Spanish furniture manufacturer iSiMAR.

The indoor/outdoor pieces are made out of galvanized steel and offered with powder-coated finishes in multiple colors. Alas, you can't really sit on the wire frames (if comfort is a concern), and the pieces look rather less good once the seat cushions are on them.

Knockdown, Flatpack Adjustable Children's Furniture Designed by Luigi Colani

As all parents know, children rapidly outgrow both clothing and furniture. In the 1970s, Luigi Colani designed this plywood Tobifant furniture set, which could grow in height along with the child.

Colani designed it to not only be flatpacked, but to be utterly easy to assemble. The joinery consists of simple wedged tenons.

The set went into production in the late 1970s, by West German children's furniture brand Kinderlübke. Today you can still find surviving examples on vintage reseller sites.
