WhiteSpace LearningLogo Design Contest

I like what you did with the lettering. How could you blend the White like you did the Space?

#84, 85, 86 Don't spend time on this one...looks like a school chalkboard which works againt what I'm trying to establish. Perhaps a bulb would be interesting if it was within a whitespace on the board...not sure, just thinking aloud

#94
The font on #83 is better

104, can you make the bulb a little more distinctive so it can't be mistaken for a paw print? But not too much different? Perhaps some type of highlight on the base?
