Ring of Fire

I've been feeding this little beauty all day, i thought the shape reminded me of the Johnny Cash song Ring of Fire:-

Love is a burning thing
and it makes a firery ring
bound by wild desire
I fell in to a ring of fire...

I fell in to a burning ring of fire
I went down,down,down
and the flames went higher.
And it burns,burns,burns
the ring of fire
the ring of fire.
