Thanks! And thanks for your great work on this design.
The UV filament is a lot of fun, but I didn't know what to do with it until I saw your clock.
The only real drawback to it is that it fades a lot faster than the glow-in-the-dark sticker (it lasts about 8 seconds). I took that picture immediately after it finished drawing the time, and you can see how much the left side of the time has already faded.
I have some extra-bright UV LEDs on order, and I'm hopeful that they'll make the effect last a bit longer.
