I was recently asked by wout (www.woutware.com) about ways to donate money to Sharp3D.Math.The best way for me to recieve money (without the banks taking most of it as fees) is simple by sending an amazon gift certificate to my email address which is eran *AT* ekampf.com.
Of course, all donations are welcome...
Btw, if you wish to donate code or have any other comments\questions about the project feel free to email me to the address above...
