I appreciate selfless hard work as much as the next person, but seriously...
I believe the P and reverse P on the coin below are the Chinese letter P (came up on a google search so must be right
the leaves (aka Eco) which sunny has used on his .org site recently are japanes maple leaves not sure how well that all nits together or whether the oriental-esk theme is any good.
Did you actually stop to think about this? There IS no "p" in the Chinese alphabet. Actually, there is no Chinese alphabet. The closest thing is the character radicals.
The character you've used, 戶, is pronounced "hù" (descending tone), and means door, family, or household.
If you don't understand the language, don't use it... if PPCoin adopted that logo, it'd be just like one of those guys with a Chinese tattoo that he thinks means "strength" but actually means "wrapping paper".
