Is it? You know what I hear from developers a lot? "I make enough money. I'm interested in solving interesting problems and working with interesting people."

So Amicus gives a small-ish amount of cash (relative to other signing bonuses I've seen), but ties in several other perks that say a lot about company culture. Each of their ideas says something about the company:

Counter Culture coffee - I didn't know anything about this brand before seeing this listing, but it appears their focus is sustainability and education.

Donated dairy cow - I've heard of this one before, and another similar program with goats. More "responsible world citizen" action.

Gym memberships - Combined with other items on the perk list, it appears that Amicus wants to provide you the opportunity to live a balanced life that includes fitness.

iPad 2 - Ostensibly for "prototyping", but really a statement that they want to provide you with tools that allow you to work while comfortable. More balance.

Iron Man Helmet - Manditory for all company events, I'm assuming. This is just fun!

Unlimited beer - The statement here is that the company is laid back and trusts you to do the responsible thing.

Fixie bike - Hipster fantastic, but who are we to judge? It reinforces the fitness/balance statement.
