Stoodle is an online whiteboard service supported in part by the CK-12 Foundation. Through Stoodle you can quickly create a collaborative whiteboard space. On your whiteboard you can type, draw, and upload images. You can connect Stoodle to your computer's microphone and talk your collaborators while drawing, typing, or sharing images.
