These icons are not a random bunch of images just put in to the program. These icons create a brand image for that program. This is part of what I wanted to talk about here. I wanted to know what animals live among your icons on desktop or where ever you store your icons.
I have my RocketDock configured with my most used icons. And from among them are the following programs that use animals.
GIMP – a Fox with a paintbrush in its mouth (or is it a dog?)
IrfanView – A red splattering of what looks like a cat.
These are the programs I am currently using more. But there are some very famous programs that have an animal in them. Specially in case of Open Source programs like Thunderbird, Songbird and definitely worth the mention is LINUX, whose mascot is a Penguin and many linux distributions have animals in their brand like SuSe which has a chameleon. BSD has the Devil, which cannot be said to be an animal.
Microsoft has few of the most boring icons; these as a rule try to depict what the program will do.
These are the icons I remember for now, will update this post once I find more. I will look stupid if I have missed some real important ones, but I leave it up to you guys to mention them here, with a link to the image.
As a departing thought, I consider Songbird to have one of the cutest icons ever!
Update: A few of my friends pointed out that MySQL has a Dolphin in its icon. Another says that all Mozilla S*** has animals in their icons. I agree.
