Holiday Greetings from LOGO Santa Claus

Greetings from Santa Claus ... a little exercise in Three.js (WebGL) based on a LOGO-like custom syntax. Although this could appear as a voxel designed object it is actually generated via a command sequence parsed using Regular Expressions. For example the head is:

S2,2Cw.US4,4.U.UCp.P8Z2S1,1.p8UP8Z-1S6,2Cp.p8P8Z1X-2S1,1Cp.RCb.RCp.RCb.RCp.p8US5,5Cw.US3,3Cr.US2,2.X1S2,1.U.X1.X1S1,1D.

The drawing syntax is based on boxes with height 1 size specified by S command, color by C command, write by the dot "." and a bunch of moving terms. Finally hierarchy is provided via anchors A#, while some spatial memory stores are based on the P(ush) and p(op) commands.

The outline effect is based on the interesting postprocessing pipeline from Three.js examples.
