Here's a font similar to ecofont: Budmo Jiggler _http://www.myfonts.com/fonts/larabie/budmo/jiggler/_ (http://www.myfonts.com/fonts/larabie/budmo/jiggler/)
It has holes in it too. Budmo Jiggler is a freeware font, it's license does not allow much openness "You may not modify, adapt, translate, reverse engineer, decompile, disassemble, or create derivative works based on the licensed font itself without Foundry’s prior written consent." I've noticed quite a bit of press for EcoFont lately. **************One site keeps you connected to all your email: AOL Mail, Gmail, and Yahoo Mail. Try it now.
