in openscad there's the $fn variable that controls the number of facetes that get calculated: https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/The_OpenSCAD_Language#.24fa.2C_.24fs_and_.24fn try reduce these and the openscad calculations get quicker.

Obviously, there is something wrong with openscad on ubuntu 14.04, my system shouldn't be that slow.
01-openscad-spirals.lua was taking 45 seconds before, now under 1 sec. ;)

Yes i7
just rendered this quickly
but just noticed, that the base of the red holder is not at the floor. needs more investigation.
I have replaced the "save png screenshot" tool button, with a "take picture with povray" tool button.
Here's my texture experiments: unfortunately my pov skills are not very well developed.
Here's a demo of the "Take picture with POV-Ray" button:
Sorry, bpp is the only 3d program I ever looked into the sources. The only one I can think of is POV-Ray itself. I wonder... doesn't have the bullet library support for this?
right -image_width/image_height*x
I know it should be that way to match the camera on bpp, so maybe it's better to keep the <-1,1,1> scaling on the image map, and take it into account for future demo scenes.
(If you double-click in the opengl view, the camera position gets set to the closest axis)
In that case, pov sometimes flips the image upside down – I don't know where to fix this.
Is it possible to add a matrix transform inside the pov camera statement?
