Well, I recently came up with the idea of a clock that actually runs in time with REAL time.

So, here is the result:

LoadSaveBlock(114373);

As stated in the labels, you may need to play around with the size of the loop to match 1 second (only for show) and the length of the 'water timer' (one length = 15 seconds).

Please do fire away with suggestions or anything =D
