I stumbled upon this project on Kickstarter:
apngasmand noticed the USD2500 pledge level:
Ports of our base APNG libraries and tools for the language/platform of your choice.
You/your company will be fully accredited. Please add SDK or development hardware
costs when applicable. Your choice of Open Source license.This could be a chance to actually get a port done by someone outside the regular Amiga community and get some extra attention to our platform from people who do not know it still exists.
I posted a project proposal on AmigaBounty.net:
