Who can tell me how the GEM imageVert object works, if it does work. PD crashes when I try it.

ImageVert maps the fake luma (RGB/3) value to a glVertex.  The brighter the pixel the higher the point.  It looks like a spiked FFT plot with lots of color.

I can get it to work on OSX, but it is pretty crash prone (something about the object creation goes awry).  I haven't gone over it much but it seems like it can be fixed up and optimized a great deal.  What platform are you on?  There are GEM developers for each that can help you with specifics.
