Lighting is a very important part of your room. Not only does the style of the lamps matter, but the number of lamps and the brightness and color of the lights can completely change the feel and usability of your room. The GE Mood Cam app for iPhone/iPod touch lets you snap a picture of your room (or import it on the touch) and see how your room would look with various lighting schemes. With a swipe of your finger, you can change the look from cozy and warm to vibrant and light. You can also use a three-step bulb finder function to select the best bulb for your fixture and create a shopping list of bulbs to achieve your desired look for the room. The GE Mood Cam app is free in the iTunes store.
