yeah we used to call them mosquito coils coz it was a kinda incense that used to keep them at bay. also good mischief material if u wanted to let a fire cracker off during school & u can be nicely seated in class when it goes off....hee hee.very nice angle & a simple capture thats quite hypnotic & brings back memories to me. :~)
Thank you all for the great comments. :) It's the bottom of a teflon pot laying around on my balcony. (It's retired from cooking since long because of lacking handle and scratched teflon surface...)
