I create iOS apps for students, children and adults with specific disabilities including intellectual disabilities and autism.
I am creating an app that will help teachers/parents explain contrasting concepts to children with intellectual disabilities or autism. I don't currently have a vision of the logo so it is wide open. It should communicate, in some way, the idea of "understanding". The cliche icon is a light bulb which might be nice, but I am wide open to other ideas. I would like the color green represented. No letters or words ... graphics only. Designers: Please make sure the icon you present is a 512 X 512 size with a 80 pixel corner radius. If you make it larger, you will need to recalculate the corner radius in proportion. Also, this is specifically an icon for an iPad app. Thank you for your work and vision.
