Bubble Blowing

[Albert]

• attach a stick and a taurus onto a controller to make a wand
• pretend to know where a mouth is (child an "empty" unity object to the hmd a few inches down, use your judgement) when the head of the wand is near the mouth AND the volume on the mic is past a certain threshold, populate a stream of bubbles
• direction could just be taurus.transform.position.forward. extra credit if it continues along the vector direction between mouth and wand
• make the world low gravity so that bubbles slowly float down
• bubble spawn as spheres, random scale btwn 3cm in diameter and 8cm
• i think there's a rigidbody setting that makes it have a lot of positional drag, which should be added as well. This drag should start low as the bubbles get vaulted forward, and then ramp up quickly
• regulate how frequently bubbles come out - a cheap & dirty way to do this: a private float (lastInstantiation) keeps track of the timestamp of the last instantiation, and an (if) statement that blocks new bubble intantiations if within 0.5f seconds lastInstantiation. Play w/ that # (maybe 0.1f seconds?)
• Bonus: add perlin noise an a per-bubble basis for X & Z component of position so that bubbles woft around a bit in the wind.

I'll probably try to implement a similar method that I used in the rain project for the frequency of the bubble. Take a look at that soon to tell me if it's a bad implementation or not
