What are some good solutions for dispensing whipped cream into swirls in a consistent fasion, maybe a specific shape etc.?  I was envisioning something just like a caulk gun where you fill the container with your cream and then squeeze out of it.  I tried googling buy all I got were pressurized cartridge bottles for making whipped cream.  I don't want it to make whipped cream, just squeeze out little swirls. 
The chaulk gun for kitchens is called cookie press and looks like this:    I know that some use it to decorate cakes and with whipped cream, too (some come with decorating tips, some don't), but IMHO it's a wiser idea to learn how to handle a pastry bag - the results will be better with sufficient practise.  But if you should have problems with your hands or simply love all kinds of "machinery", the cookie press might be an option worth checking out. You can either "pull the trigger" for a pre-defined amount or unlock it and simply push the plunger.
