Morozoko Forge produces ice baths for cold water immersion--for example, for use in the Wim Hof method to breathing and cold therapy.
The ice bath works by leveraging the bather's natural antifragility. Like the ancient mythical water beast the Hydra, which grows two new heads every time one is cut off, the bather becomes stronger as a result of exposure to stress and pain. We're seeking a logo that illustrates growth from stress and trauma. This graph is a metaphor for the process https://goo.gl/images/i1oHTp
in it, the x-axis is the water line. Underneath the ice water there is pain. Emerging from the water is the neck and fearsome head of the Hydra, in the shape of an exponential growth curve.
We imagine three different curves: steep, less steep, and long term. The steep might level out to form an "S" while the others bend up. The represent the three paths to continuous growth, and each is a Hydra head. When one growth path discontinues, two more begin.
We want a logo that illustrate this metaphor.
