A nonnoetherian singularity may be viewed geometrically as an algebraic variety with a positive dimensional 'smeared-out' point. I will describe how isolated nonnoetherian singularities admit noncommutative blowups which are smooth, in a suitable geometric sense. Furthermore, I will describe how a class of isolated nonnoetherian noncommutative singularities, namely non-cancellative dimer algebras, also admit noncommutative blowups which are smooth.
