Ideas to get forward on this.
First of all i would feel way better, if you, rylan, would post pics/vids/source/etc. of the current version of the peachy.
I think this is the best way to show the world, that peachy was not a scam.
If you have all parts except the lasers, would it be possible to ship these? if so, i would pay the shipping by my own.

You put a lot of work in the "sorry-video", now try to keep your head up, look to the goals you have reached.
And show every developed part, every fixed problem, every discovered issue to the world.
That would give you and us a better feeling.

On the money-side, if i get this right, you now have a 300.000$ claim on David.
So, why dont sell this claim. You would not get the whole money, but maybe 70% (dont know what the market is paying there...).
And someone who knows how to get his money would deal with David.

Hope Peachy is not dead!
