I would probably include apps like:
Google Docs as those tools allow us to collaboratively create documents and/or presentations.
Wikkis as we can collaborate to synthesize our knowledge about a topic on a shared website.
What about Picnikwhich allows us to modify photos in many creative ways?
Maybe Moodle (or Wikkis) since it allows one to synthesize a number of resources in order to create courses. -- like what you have done with Wikkis Mike.--you have created several workshops or courses by synthesizing a variety of resources into one spot.
Podcasts and Vodcasts could also go here depending on whether the content is a synthesis of several sources which captures the audience attention with effective communication and voice.
What about Youtube? Several of my students create videos and upload them regularly to Youtube. How would we decide whether the product is "creative" or not... Maybe it's not creative or not--maybe the question is -- to what level is it creative? Does it have foundational knowledge that is built upon? Does it promote new insight in the viewer? ...

Paula and I had a discussion about creation vs. creativity. I think that will be a huge component when the rubrics are's something we're definitely thinking about! -Mike (An educational account will make it more viable for individual students)
Using graphic/sketching software students can upload their designs. Laser cutters transform student ideas into flat packed or two dimensional objects that can be assembled from a large range of materials. These can be sold within Ponoko as each student designer/maker has a shopfront web page to market their goods. I love the Glogster uploaded under Remembering Id like to have a go for this wiki and do the same...Ive never used Glogster til tonight.

Feel free to GLOG away! It's a great tool, and I use it in workshops with teachers when I'm teaching digital storytelling and multiple modalities. -Mike
