I Love Zurb's Foundation framework, and wanted to combine it with a few other tools to make it even faster to prototype a site.

• Added in most of Andy Clarke's "320 & Up" boilerplate. Of particular interest is the global colour palette, which allows the whole colour scheme to be changed with one variable. read AC's blog on Less.css, Colour Palettes
• Added in the Text em calculator he has so text-size("x") outputs both px and em units

Credit to Justin Marsan for the inital Less port of Foundation and credit to andy clarke for the great ideas on colour palettes. also included is "Less elements"
