Dale, I understand that some artists would use the prop to simply create innocent looking images. Some biologists may use it for scientific reasons. But like stemardue said, the original post doesn't evoke an intention to use it for either artistry or science. Maybe I was more critical after finding out Gon2 has a science background. Scientists can often be more critical of people in the same field. (If you want to see someone really get vilified then attend a forensic science convention and you'll hear constant slams against Fred Zain.) I've been involved in scientific research both as an undergrad and a graduate student. Gon2 later stated that the request was for a teaching aid. That's fine. But it's in good taste to present that kind of information upfront. At least, that is how I was trained to think through my scientific experiences. Since this is not a scientific community, I understand that everyone else's reactions to Gon2's request may be different.
