Is there a way to install a Yosemite theme on mavericks? Without Flavours?

I have Mavericks on my mac and I want to make it look like Yosemite. Is there an alternative to Flavours (my trial period is running out) that will allow me to install a Yosemite theme for FREE?

I found out about Flavours here: http://nssenterprises.blogspot.com/2014/12/how-to-make-mavericks-look-like.html

If you have Flavours copy the link below (auto-link does not work)
