I just now got in to rainmeter and like it so far, but my setup is 100% barebones "I have no fkn idea how this works yet." Curious to see what some other rainmeter users are working with and maybe get some ideas for mine.
Right now I'm just using the Enigma theme with two sidebars with the skins I felt I needed and added a third-party weather skin that looked better than the one Enigma came with. I'm also still using RocketDock until I can figure out a rainmeter equivalent since I like having all my application icons on my desktop but in tool-bar form(like the pre-vista/7 movable quicklaunch that Microsoft decided wasn't necessary anymore). I also incorporated some other skins/modules from the other two complete themes available from the rainmeter homepage. Being able to mix-n-match really makes this awesome.
