Hello... :)
Actually, we are the designer community and the admin of Logotournament talking about the using cross or plus/positivity mark right now as a symbol of the medical icon. There is a kind of discussion about this, a new rules that would be applied absolut. So in case that the result of discussion will be revealed, and Is it " Allowed " or not "Allowed" to use cross/plus/positivity, i will tell you later.
But for now, i think we are all designer still using it in the contest.
Apparently among all the designers still wait it too, about the final decision for the rules to use it.
So, that's why i use another idea...as the new option.
it's the waves or impulse of heartbeat to show Life, that quite strong too in showing the medical icon.
I'll revise the cloud too...
Thank you for your attention!
Regards
