A little fun...
the flow would be this one:)
Copy Macros that you have somewhere : 30 seconds if you have well organized files....
drawing a circle: 5 seconds....
calculation: 5 seconds
rendered: 3 seconds in your favorite render engine (mine free one: Simlab composer Maxi 1920*1080)
So one minute when not awake! And the programs not open! :)

An informed eye will of course see that the number of polys at the save was a little insufficient so 3 seconds more of paremetering! :)
