Here’s a cool iPhone App called Light Writer that lets you make cool lighting effects by waving your iPhone about in the air.
Light Writer uses POV (Persistence of Vision) effects to display messages that you have set up on your iPhone, a great way to communicate with your friends.
How Light Writer Works
The Light Writer app leverages the concept of Persistence of Vision (POV), a phenomenon where an afterimage persists on the retina for a fraction of a second. By rapidly moving the iPhone in the air, the app creates the illusion of a continuous image or message. This is achieved by displaying a series of light patterns that, when moved quickly, appear as a coherent message to the human eye. This makes it a unique and innovative way to send messages or create visual effects.
Practical Uses and Fun Applications
According to the developers, the application works best in photos, so now you can take some fun photos like the ones above. It certainly does look like a lot of fun. Imagine being at a concert or a party and using Light Writer to display messages like “Happy Birthday” or “Congratulations” in the air. It can also be a creative tool for photographers looking to add a unique element to their shots.
No doubt we will probably see a few photos on the web over the next couple of weeks with funny messages. The app can also be used for more practical purposes, such as signaling in the dark or creating eye-catching advertisements. For instance, small businesses could use it to display their names or special offers in a visually engaging way during nighttime events.
If you want this cool iPhone App, it is available from iTunes for $0.99. The low price point makes it accessible for anyone looking to add a bit of flair to their photos or messages. The app is easy to use, with a straightforward interface that allows you to type in your message and start waving your phone to see the magic happen.
