Overlay own effects for 5min for progess bars w.g

Hi freaks,

anybody with suggestions how to realize this:
I have a vertical strip with 60 LEDs. The “drip” effect is perfect, but i want to use it as a timer - the bottom leds should fill until the bar is complete filled. I want to use it as a timer.

I think i need some external programs - but i found nothing with those dripping effects. Above that, the time should be adjustable. Anybody with some good ideas how to realize this ?

The dripping animation should interrupt the WLED effect and after completion it should continue. Therefor i think, an external script in python e.g. should be best.

many thanks,
