Thanks for the look and feedback, Paul. My aim with this design is to be suggestive of all the relevant points yet maintain a 'clean' and attractive look. I personally do not feel neurons to be a graphically attractive element and they almost never look as intended at smaller sizes. As for your suggestion of electrical discharge - that's pretty much what the asterisk is meant to suggest (that and the AHA of comprehension). Perhaps I can change the shape of it to be a bit more spark-like...Stay tuned:)
I like this. It's suggestive of both neurons and synaptic firing but still 'reads' well graphically. I also like the added suggestion of a fuse having been lit - light a fuse in a young mind and watch what happens...
looking better. also, show me a design with the brain to the left of the wording. This will fit better on letterhead and business cards. That is, brain of left with wording all on one line next to it or brain on left with wording on three lines next to it.
