Launching "." with gravitons?

[Floorface]

The two might be related. My guess is that when the random smoke particles are created, it counts as an object, so much like how you can see windows hit by smoke clouds sometimes, the graviton accelerator is throwing the smoke at the window.

However, the smoke doesn't persist for more than a millisecond, and it doesn't fade out either. It just disappears abruptly. The only thing I could think of is that some smoke has the property to produce items like chocolate. If it just being generated without any reagents but has that property then perhaps that explains the existence of ".".
