I wrote one that I keep in a textfile to cut and paste when people ask about it in the Help Forum:
Humming Power Crystals come from the Fragmentizer.
The fragmentizer can turn items in your inventory to crystals, which you can then use to buy items from the Crystal Shop. You can fragmentize any restockable (i.e rarity 1-99) item. Fraggable items will show as clickable pictures when you're at the Fragmentizer.
Not all fraggable items will always give you a crystal - it's based on rarity. If you use common, mundane or normal items I recommend you only use VERY cheap ones, as you're likely to get no more than three crystals per ten items.
If you're fragging multiples of the same item, you do NOT need to click back every time; you can just keep hitting Refresh till you run out of that item.
R65 and under: 0-1 crystals
R66 - R89: 1 crystal
R90 - R98: 1-2 crystals
R99: 1-3 crystals
To spend the crystals, they need to be in your crystal bank (there's also an achievement for having 1000+ crystals in your bank). They cannot be removed from the bank, only spent on crystal shop items.
I hope that helps :D
