Hm..
Knowing that about A3 makes something I saw when I was little make a bit more sense.
My dad had taken me to a comic shop that also had a lot of movie replicas, at the time I was obsessed with star ship troopers and they had the figures there as well as props. On one of the doors in the back of the shop was a (I want to say) life size plastic version of Ripley from A3 with hive material all over her.
I didn't know what the hell it was at the time, I don't even think I had seen Aliens yet at that point. I'm not to sure why it was Ripley covered in it though, I've only seen A3 twice and I don't recall anything like that happening.
