Here are funny icons from Martin Berube (other icon sets of him here) if you plan to build your components or clusters in Grasshopper. It somehow became a fashion of Rhinoceros, to give names of animals to products, that at first seemed to be only the species in danger of extinction. (maybe I am wrong but it is a fact that %85 of Black Rhinos were killed in the past 25 years) However, this tradition seems to be changed eventually and come to a point that you should give a classy name to your product (not dog, nor cow) while reflecting the functionality of your code as a bonus.
