seeing as i have been too lazy to get an additional "ring" i needed to do the first experiment 100% reversable.
the ring is done with "black-out tape" and the lip is done with some vinyl i had laying around.
the lip is actually gloss black.
i will get some flat black vinyl and re-do the lip.
i will post a better out door pic later.
that pic was in my flourecent lighted garage right after i finish the lip.
