While crossing number is the standard notion of complexity for knots, it is hard to compute. The number of ideal tetrahedra required to construct the complement provides a natural alternative. Callahan, Dean and Weeks determined knot complements with 6 or fewer tetrahedra in SnapPea's census of cupsed hyperbolic 3-manifolds and explicitly described the corresponding knots. We extend their hyperbolic knot census and identify all knots whose complements have 7 tetrahedra. We obtain 129 knot complements out of 3552 orientable, cusped hyperbolic 3-manifolds with 7 tetrahedra. Many of these ``simple'' hyperbolic knots have high crossing number. We also compute their Jones polynomials. This is joint work with Ilya Kofman and Eric Patterson
