That's hella good for being a quickie! And especially on a white board! I always have a time of making those dry erase markers do what I want. :D

if your actually trying to do something with them the markers can be like painting with elephants >.>.. if your really quick and just leave everything as you draw it ( unless its glaringly wrong ) things turn out okay :) my favorite part is also my most hated. you can erase with just about anything.. so if you wanna add that little sparkle in the eye or a gleam on the wet nose ( or other wet things) it's easy you can even use the cap of the marker but if you mess up its impossible to put it back without redoing the nose or eye all together >.>

I hadn't even thought of the ease of removing the marker being a positive thing... but now that you mention it, I can definitely see it! Makes me want to play around on a dry erase board now. :3
