The direction we're leading with the logo is that we imagined a conductor (think orchestra music, not trains) from the back, conducting a group of people. In our software, we use icons of people similar to the style of msn messenger... weebles? http://www.techshout.com/images/msn-icon.jpg
The president of our company things that a shiny, fresh person with a conductor's wand? directing a group of smaller people (children in a classroom).
The logo will be placed in the header of every page on our software, so we need it to be clear, scalable (SVG / Illustrator based), and POSSIBLY inside a shape like a circle, shield, etc... that part can be left to your creative imagination.
It needs to be clear, fresh, and promote innovative communication, and bring a sense of safe, caring environment for the children involved.
Thanks for your designs, and good luck to everyone!
