The Interactive Sign Language Fingerspelling Screensaver is a useful tool to increase signing skills.
Fingerspelling requires continuous practice.
The screensaver acts like a live practice partner, so that you can train yourself to read a word not just as a single picture, but as a sequence of signs. The Lite Edition includes the alphabet as well as a list of musical instruments. You are asked to fill out a registration form with name and e-mail address before downloading.
