This great site generates a cloud map based on text that you enter or paste into the field. The more frequently a word appears, the larger it is displayed. You can manipulate the image layout, colors, etc. There is no registration required. The only downside- you must use a screen capture utility to grab the image!


This cool site allows you to draw on a whiteboard in multiple colors. It also allows you the ability to vocally narrate what you are drawing- if you wish. This would be especially great for showing math solutions or explaining diagrams of various concepts.
