born in Ambon and lived there (on and off) till '98 when things got heated. then lived in Jakarta for a while and then Papua for about two and a half years.. now I'm State-side for college. most of my knowledge is from older videos of the place that I saw while I was in Papua, and memories of Ambon from when I was younger.. which is why I said "I could be wrong".. anyways.. as for ingenuity..? well the Malukans make some of the best wood boats out there, or so I've read. the kids in my neighborhood always make little "spear guns" using rubber bands and broken umbrella parts. and an old military man who used to live next door had a couple spear guns like what you have pictured, but shaped more like rifles, with stocks and all... that's all I can really remember right now, but I'll ask my parents if they can remember anything as they'd be more likely to.
