Holography actually sounds pretty promising but the issue is that most holography systems are phased (they trace the hologram with a single laser.) If a holography with hjgh energy could heat up the inside shape of a liquid in a beaker, it could turn it into a solid. The issue would be thermal diffusion but if a dense enough liquid were used, it could work!
