You can explore it by magnify a block by select and double click in it.
Following is the coresponding scene script for the above ray tracing fractal.
It's writen in JScript grammar.
You need not paste it to the FMF.
Just switch to Property Editor's Color tab and click the toolbar's last button to view or edit it.
