Hi baguslogo,
Thanks for your ideas. Can you try some more variations on #12? It looks like a particle (maybe a neutron!) has passed through the "ENDECTR" and struck the "A," resulting in a starburst or something. Very cool. Could you try some diifferent fonts, try different shapes of the "A," and maybe add a new color in the first "E" and the "A" to link the "source" and the "sensor"?
Thanks!
