The style of this tubular type effect came about whilst experimenting with overlaying circles over each other to create a cylindrical effect, the result being a three dimensional looking form with circular ends.

The form of the font itself was inspired by the free font "Hero" by Fontfabric as it incorporates a linear and sleek perpective to align the circles to.
I have created a successful working font from this but it is not yet  being distributed (request only)
