This Double Trouble ambigram is a medium length asymmetric ambigram that may seem impossible since the words contain a different number of letters, but here it is.
Take a look to the left, and you will see that this design says 'Double' one way and says 'Trouble' the other way.
To rotate the design, just move your mouse over the image.
