Your Roomba can do double duty as an air-quality tester and even a cat transporter, so why not a fragrance factory too?

Robot Add-ons has a nifty little accessory for your favorite robot hockey puck: RoomAroma is a stick-on fragrance that sweetens the air in your home while Roomba cleans up.

It's quite an innovative way to improve your air without bothering to plug in air fresheners, and it attaches to Roomba in a snap. It's no wonder the two guys behind Robot Add-ons are from iRobot. … Read more

Food generally isn't too big of a deal in the "Star Trek" universe unless you're talking about tribbles eating all the quadrotriticale or Picard ordering up a hot cup of tea to go with his space scones.

All those Enterprise crew members still have to eat and that means there's going to be some hot food coming out of the replicators. That also means you're going to need a space-worthy oven mitt. A Spock oven mitt. The $14.99 oversize Spock hand has just enough blue uniform on the cuff to designate its rank.… Read more

I've been to some bizarre spots in South Korea, from DMZ tunnels to a seaside park dedicated to giant penises, but a new theme park in Suwon is at the top of my must-see list: it celebrates toilets.

The Restroom Cultural Park is billed as the world's first toilet theme park. It's a monument to the colorful former mayor of Suwon, a man known as Mr. Toilet.

The late Sim Jae-duck was himself born in a toilet and had an affection for loos throughout his life, rigorously promoting public facilities while mayor. … Read more

Halloween's over and done with, the cold November rain is here, and the mercury is dipping. But the gadget ninjas at Tokyo's Thanko do not rest.

They've been preparing for winter, when millions of Japanese face less-than-cozy conditions at home and in the office. Central heating doesn't really exist in Japan, so people use everything from kerosene heaters to blankets to keep warm.

Add to that Thanko's USB Heated Futon Mouse pad.

This cute twist on traditional futon floor bedding, which is, of course, very different from the Western concept of a couch futon, comes in three parts: a mouse-pad mattress, a heated quilt, and a wrist pillow. … Read more

The Ostrich Pillow personal nap tunnel already gave plenty of people the heebie-jeebies. Now, there's something even stranger invading the napping-accessories market. The UpRight Sleeper is a modified neck brace that holds your head in place so you can snooze while sitting.

The contraption is adjustable so it can sit under your chin or go up around your forehead. It moves around to accommodate different head shapes and sizes. A back strap is trapped between your back and your seat to keep everything in place.… Read more

Kick back in your rocking chair. Relax. Knit some booties for your basset hound. Blast some AC/DC through built-in speakers and recharge your iPad at the same time. You have an iRock, an iPhone and iPad-charging rocking chair.

Though it's still listed as being under development, a lot of details are already available for the iRock. It comes in five colors ranging from white to bright red. It is made from Swedish pine. It has a very classic shape. There's no attempt at making the rocking chair look like it was built by Apple's design team. That's pretty refreshing.… Read more

Lightbulbs. Simple, cheap, and easy to replace, right? Not anymore! Philips is dragging the humble bulb into the future with its "Hue" technology -- wirelessly controlled light orbs that give you complete control over the lighting in your house.

The Hue bulbs look like ordinary lightbulbs, and screw into light sockets as normal. Inside each bulb, however, is a wireless transmitter that communicates with a hub you plug into the back of your router.

Once connected, you can use a Web site or download an app (the iOS version is out now -- there's no sight of an Android version, though Gizmodo reports it's coming in December), then use the wonderful power of the Internet to fiddle with the lights in your home. … Read more

You may have had a cool treehouse as a kid, but would you want to spend more than five minutes in it today? Well, try spending the night in this deluxe pod that hangs from the branches.

The Cocoon Tree is a spherical tent formed by 24 aluminum rods. It hangs from polyester ropes tied to trunks and branches, and has a net below for access and safety.

The tent weighs about 130 pounds without anyone in it. The structure itself can support more than 2 tons. The ropes can bear loads of 1.6 tons, and there are six … Read more

Stained glass is usually associated with Sunday mornings, proper attitudes, and at least a hint of guilt.

If you happen to worship at the altar of Marvel, though, Etsy seller MartianGlassWorks has the perfect accessory for your alternative cathedral: a 47-inch tall Iron Man stained glass window -- just one of a collection of brilliantly rendered, geeky glass creations.

The Iron Man window, which apparently took over 100 hours to construct, uses 334 pieces of glass in 11 different colors. It will set you back $4,500 to possess this artistic wonder, but that's much less than an actual, working Iron Man suit.… Read more
