So in Sweden, there’s a thing called the TreeHotel which is a few treehouses that you can pay them to live in. As if that weren’t stupid crazy enough, one of them is made entirely out of mirrors, which makes it reflect everything around it and gives it the appearance of being “invisible”.

Of course  there are other treehouses, like one that looks like a birds next and another that looks like a lego house, but no matter which one you decide to stay in, you’ll have to get yourself half way around the world to do it since the hotel is in a forest 40 miles south of the Arctic Circle, in Sweden.

Moving on, At historypin.com you can take old photos and pin them onto a map so that people everywhere can see where certain events took place.

While it’s not all coronations of kings and births of presidents, there’s a lot of interesting stuff to be seen that helps us keep in touch with our shared past. Taking this idea a step further, teams from MIT and Adobe are coming up with a way of automatically pinning old photos to new ones that you take.

The software they are developing helps a photographer figure out where to stand and how to hold the camera in order to snap a shot that is similar enough to a photo from long ago to allow you to play one over the other. It’s like a visual time machine (if anyone watches Fringe, this is a familiar idea but only instead of an alternate universe, it’s old snapshots. Still cool though.

Right now, the software that helps you do this runs on a laptop connected to the camera, but in the future they hope to make a version that can actually fit inside of a camera.

Finally, did you know that making stuff for the internet costs money?! Well it does. (Make sure to click the ads, thank you very much). The way most companies make money on the internet is by showing ads. Annoying, poorly targeted ads. And they rake in 25 billion dollars a year doing it.

Most of that money comes from ads placed by Google, but Bing is hoping to be able to do what Google does more effectively and with fewer ads.

It all has to do with how they figure out what ads to show you. An example from a Technology Review article goes like so:

If someone searches for the word car, some simpler search engine algorithms might show ads for motor oil or snow tires. Bing, using a new technique called  AdPredictor, and artificial intelligence kicks in and figures out what other variables might come into play. For instance, if it’s a weekend morning and it’s summer, people are more likely to click on an ad about stuff relating to changing a cars oil than putting on snow tires since that’s when you’d be most likely to want to do it. Makes sense, and hopefully that means fewer ads (which you should click on. Now).
