Noisebud have set up an Indiegogo Campaign to fund the development of OS X and 64-bit versions of their VST plugins.
They're also asking for help with suggestions for new features and improvements so you'll have a chance to influence the final result.
One of the more expensive perks even let you name a plugin and also decide what it should do.
You'll find the campaign here: igg.me/at/noisebud
