Instructional Technology... What are you excited about?

People who love technology- love to find new resources and share them with interested parties. My latest favorite find is VoiceThreads http://voicethread.com/. This is cool website which allows users to participate in a dialogue around an image, or series of images. It's almost like photostory meets blog meets chat room meets you tube. There are lots of instructional implications for this online resource. Students can create presentations or participate in online discussions, or voicethreads that others have created. These voicethreads can then be packaged up for later use or assessment. COOL! What have you found lately? How might it be used as a tool for learning?
