This latest theme from Visto Themes has some nice and large icons and a really slick header bar. I am not the biggest fan of the bland background but that is easy to change. The large icons are a matter of choice. Personally I like the smaller ones but the larger ones are easier on the eyes. Especially if you only use 18 or so icons compared to the 24 usually found in smaller icon themes from Visto.
All in all this is a nice and slick theme. I loved the nice and clean homescreen. The colors of the text are perfect and easily allow you to change the background. You can pick it up for $6 from VistoThemes.com.
