Hey John, this is neat! Speaking to grad students at Columbia in both the math and physics department, I could see something like this really solving a problem. What led to you making this/what makes it different from every other whiteboard app on the web?

Thanks! I started making this after I bought a Macbook Air to replace my old Lenovo tablet PC. I really missed being able to draw precisely on a computer (which was possible with the tablet PC) and standard mouse input just doesn't do it for me.

Compared to other whiteboard apps, we're really focusing on alternatives to drawing with a mouse. My favorite feature (and possibly our most distinguishing feature) is the webcam scanner. It makes it really easy to scan a sheet of scratchwork and then rearrange terms and delete mistakes on the computer. Plus, it doesn't take a long time to draw the expressions, because you can do that with just pen and paper.
