CloudRackLogo Design Contest

We like these designs. Instead of a server rack could you show an option which is education based?

On your entry #51, can you make "cloud" bolder than "rack"? We like how the first part is bolder than the second. Also, can the end of line the pencil is making somehow be lit up like it's also a fiber optic cord? Maybe put a plug at the end like in entry #50 or dots like in entry #4?

additionally, could you lose the part of the cloud on the right side of the pencil? Maybe too much cloud now.
