I had no idea that transparent wood was even a thing-- and here it is being improved.

Wood xerogel for fabrication of high-performance transparent wood - Nature Communications
Optically transparent wood composites are commonly prepared by delignification of wood and subsequent infiltration of thermo- or photocurable polymer resins but the fabrication is still limited by the intrinsic low mesopore volume of the delignified wood. Here, the authors report a facile approach to fabricate transparent wood using wood xerogel which allows solvent-free infiltration of resin monomers into the wood cell wall under ambient conditions.’
