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.
