Please see attached sample that was found on this site for reference (design by inancz), I have also attached a traditional yinyang symbol showing the direction of energy:
We are looking for the yinyang symbol to be two dolphins, they should be travelling in a counter clockwise direction (opposite of the example).
The dolphin on the top or blue colour should be flexed as if jumping out of water and the bottom dolphin should be reversed as if swimming below the water.
Tails can be dots that you would see in traditional yinyang symbol.
Please also include some kind of water element as shown in the example.
Name of the device should also be included: Dolphin Neurostimulator
Use your imagination for colour scheme, traditionally we have used blues and burgundys in our Corporate logos.
