Abstract
We prove full Hausdorff dimension in a variant of the Kakeya problem i nvolving circles in the plane, and also sharp estimates for the releva nt maximal function. These results can also be formulated in terms of the wave equation in two space variables. A novelty in our approach is the use of ideas from computational geometry.
