Check out the plane's interior for your next flight
Sitting for hours in a cramped metal tube isn't generally much fun, unless you have pockets deep enough to hang out in first class. If you'd like a more comprehensive look at the plane you've booked yourself on, then Seatguru can give you airline seat maps, flight updates and photos.
In addition, previous fliers are able to comment on particular craft or flights.
One of the coolest features available on the website is a Beta comparison service between different economy flights. The prices vary -- as does seat width and leg room.
Design and order your 3D-printed creations
3D printing is becoming established as a construction method in everything from art to architecture. Health professionals have used the technology to build innovative prosthetics for children, firms offer 3D models in replace of pregnancy ultrasounds, Japanese companies use it to create miniature dolls of citizens and New York officials are panicking over 3D printed weaponry.
For the average consumer however, there is imateralise -- an online service which lets users upload or sell 3D designs for manufacture. With designs for jewelry to artwork and transport models, the upload and print service is useful if you want to give someone a more unusual gift for their birthday this year.
Hunt down and buy leftovers
If you want the comfort of a home-cooked meal and haven't the time or energy to do it yourself, then why not track down neighbors who are willing to sell you their efforts?
Shareyourmeal.net is a food-sharing network. Started in Amsterdam in 2008, the network has expanded and is soon to launch in New York.
