Very cool fully online graphing calculator. They are VERY interested in working with teachers to make it a great classroom product. It is free and "always will be" (per the inventor). It's wonderful and great for projecting in the classroom. Haven't tried it but I think it would be great with a smartboard.
Allows you to add hotspots on any photo or image. You can have the hotspots give more information about something in the image, show a video or another image. These images can then be embedded into your class website or blog and they will retain their interactivity.
Think about using this as a cool presentation. Add hotspots to a map to discuss history or a lit trip. Add it to images of art with zoomed in hotspots highlighting the paint and items in the pictures. It's great.
