very nice, krish! i worked on a tadpole image last night and came up with a very similar graphic representation
As i worked on it i too felt adding noise and taking out the color worked well for my 300mm tadpoles -- and then, here's yours! we've almost shared a brain. i'll upload mine and you can see what i mean.
CNP might just have a tadpole series going - like the elephant series.
superb stuff. thanks,
