#17- yes, indeed - fun, hip and scalable... I picked # 17 because I like two colors in the font and the posture of the jack but note that i also like the 'movement lines' in #19... I like the way this one lays out but the spring is a little whimpy and will be hard to see as gets smaller. also note I see the character standing alone in places (on the website, etc) so would like to see him popping out of a box too perhaps with a stronger spring? Also - drop the "inc" (not needed in the logo) and thus, maybe, move the Network to the left (could even shrink if needed) and put a box where the inc is and possibly some movement lines (like streamers) coming from the box as well? Check some of the logic here
