Simple, Obvious, Elegant, Love, PLAY. A logo that tactfully contains a symbol that is easily recognizable as a heart (stylish and unique, as far as possible from a cheesy heart). At the same time, the logo also contains or is in the shape of an obvious play button (without the words play, just the triangle symbol).
The logo must look amazing large on our splash screen (great, subtle detail) as well as shrunken down, as a PLAY button on a media player on your iPhone (or Android phone).
Extra credit for figuring out how to morph the small button into a PAUSE button that shows the same heart, growing or healing itself. An animated logo?
The splash screen of our app will use the large heart logo and PLAY symbol, scaling down into the PLAY button of our player. It's the same logo, same graphic, just smaller.
Extra extra plus if you somehow capture the essence of our company name, the Love Experiment, and the concept of experiments, labs, etc.
Please ask for clarification.
Also, I adjusted my preferences to be dead center, because I didn't want my stylistic biases resulting in a design that is too youthful, playful, or feminine, or too anything. We want universality across cultures and people. No words!
New: the logo below is an old logo of ours for our company, which was also made into a pendant. I'm including it for inspiration only. Keep up the great work!
