I like to design wordpress themes and change my site look, sometimes as often as twice in a month. To help me with this, I have incorporated a plugin called theme-switcher.
Below is the details of the plugin, if you are interested.

Now because of this penchant of mine to design skins, my theme folder is littered with several themes, which I don’t want to show. So yesterday, I sat up really really late, and selected 4 of my favorite themes, and moved the rest. If I used the plugin as-is, I would end up displaying the i-phone skin as well, with a theme selector. I didn’t want this. So I ended up tweaking the presentation via CSS to give me more creative control. I then ended up with the color grid (see below) on each of my skins.
Voila!, I now have four skins for my site… Neat or what?
