Yup 2 triangles per blade. The texture fades from opaque to transparent on the u
axis, and from yellow to green along the v axis. Each blade is mapped with the
same v value on all corners, to pick the colour of the blade, and with the u
value setting how opaque it is.

About 2 hours for this image at 1600x1200

250,000!
The bliss image rendered a lot quicker even though there were more blades,
because I created a mesh of 100,000 blades then duplicated it 40 times with
small random displacements. I couldn't do this on this scene because the object
is so complex that it became obvious some of the blades weren't touching it, so
this actually has 1 mesh with 500,000 triangles in it!
