My guess is that Ockham used an internal (P8 type) emitter.  Try viewing the heart obliquely through a refractive pane of glass.  What is the white band at the top of the mirror?

     Ockham, how did you do your emitter?  Nested inside the visible neon?  How did you set the pp2 properties checkboxes for the neon and for the emitter?  Or did you manage to flip some internal toggle to prevent the camera from viewing the emitter?

     By the way, the kitty neon has both an internally concealed (P8 type) emitter and an overlaid (P9+ type) emitter, so y'all can choose which to use.  I haven't gotten the thing packaged yet;  I've been fixing hardware.  In this old Dozer chassis, the processor is liquid cooled, but I fried the RAM.  So, replaced the RAM -new RAM has anodized heat spreaders- and added a rear case fan (blue) and dual fans blowing over the memory (white).  True to her name, Phoenix has arisen from her burnout.

PS  If you want to see detail, open the image in a new window, then look for the little magnifying glass icon down in the lower right corner and click it.  When the new view opens, click the magnifying glass icon a second time for full size.  The RAM fan set is GSkill's Turbulence II, about $15 US.
