This Future Present ambigram is a medium length asymmetric ambigram that is a nice generic design that makes you do a double take.
A quick glance will show you that this design reads 'Future' when upright and reads 'Present' when upside-down.
If you can't read upside-down (without breaking your neck!), rotate the entire design by mousing over it.
