The reference with respect to "familiar looking" had to do with having seen the pictures before.;)
When I look at an item, such as an action, I look at every aspect and dimension as a newly created mechanical item. All I see is a well thought out and designed Raptor. Never even crossed my mind that it was anything other than a Raptor.
Kinda like looking at different quarter horses. They all have 4 legs and a head, but......some, like the Raptor does, stand out immediately as being totally different and a cut above the rest.
