- We show that dynamic, feed-back controlled optical traps, whose positions depend on the instantaneous local configuration of particles in a pre-determined way, can stabilise colloidal particles in finite lattices of ${\it any}$ given symmetry. Unlike in a static template, the crystal so formed is translationally invariant and retains all possible zero energy modes. We demonstrate this ${\it in-silico}$ by stabilising the unstable two-dimensional ${\it square}$ lattice in a model soft solid with isotropic interactions.
