Before PowerPoint, there was the overhead projector, and you may well remember its use in the classroom when you were growing up. Whatever happened to the overhead projector? It grew up and became the WolfVision Visualizer. This straightforward, user-friendly presentation tool still has its place in learning and teaching, and WolfVision keeps making it better. Its third edition of the Visualizer VZ-9plus boasts a more elegant design and housing, simplified operation and improved picture quality. And it is ambidextrous – accommodating to either left-handed or right-handed operation. Visit www.wolfvision.com and tell them Thorburn Associates sent you.
