I've been working with digital manufacturing start up Ponoko and we've been working on a few ideas of showcase products that can be easily made through our service (such as a wine rack and a spinning top).
I thought of creating a simple but stylish lamp that could be personalized with your own patterns and images. Lamps are great objects because they allow you to play with light and potentially project shapes across an entire room. Laser cutting is perfect for creating this type of object because it allows you to get a really high quality finish and fairly precise detail while keeping costs as low as possible.
