Voice Painter software from New York-based VisiSound Technologies translates vocal fluctuations into colorful images, allowing users to create works of art with their voices. The program makes a great activity for children's events — kids can sing into a microphone, then watch as their voices create swirling patterns on a screen. Post-event, the “voice paintings” are posted on the Web, where they can be ordered in a variety of gift formats, from T-shirts to greeting cards to glass paperweights.
