#51: This one is my favorite out of those you have posted. Do you think you could make the logo a bit more like an EKG reading (http://www.meddean.luc.edu/lumen/MedEd/hmps/ekg.jpg) and have the image drop into the text a bit, so the two pieces are a bit more integrated? Also, can we see it with red instead of blue?
I still like the idea of the EKG, but I am not sure we captured it in #54 or #53. How about we try something with a black background (ignore what I said about white before) and continue using that blue that you did in #51. Instead of the blue ball/orb, could you use the small circle with the "halo" effect (like in the link I provided before)? If necessary, let's drop the tagline out completely and focus on the company name and logo.
