I have a design/ interior design project where inside glass tubes are some bulbs and I would like the light to go from on the off slowly (reproducing the beating of the heart) and progressively actually. I really don't know how to produce this kind of effect or even if it is possible? Becausethere will be several tubes and all of them will have a different "pace" but still progressively.
Any help would be awesome.
Thank you very much
