#41 is a very clever concept. I like where this one's going :)
I definitely prefer the pencil on the right. I could see situations where we would use the tri-colored version and others where we would use the all-blue version, but for now let's stick with the tri-colors. I also prefer the speed gestures to be there (it looks unbalanced without them).
This logo presents itself well in color and black and white, which is important. Not sure how to suggest improvements without adding too much to it. Simple is good. Also, no need to worry about the text, as we will be doing that independently from the logo.
