Two mod ideas

[vitusweb 25]

Hi,

I was wondering whether those two ideas would be feasible and would like to ask mod specialists. 

1. Functioning clocks. In principle, it shouldn't be difficult to link the rotation angle of two props (clock hands) to the system time (or to the game time, I would leave both options).
2. Functioning fountains with jets of water. As there is already a mod for dynamic fireworks, it should be possible to use particle systems for that as well. The main difference is that the objects shouldn't have a finite duration, but run in an infinite loop. Would that impact performance significantly?
