Time or heat/waxed Bamboo blocks

The Adding of at least two different colour versions of bamboo blocks, slabs, WALL etc (including just adding those in general) One waxed to keep its green colour. One either put into a furnes to dry out or leave it to dry out over a few days to turn it a light tan colour. Similar to copper blocks. You could always add a darker option if it's a time one like copper block, so have a tan and a mottled brown? Make them directional placing as well for versatility and keeping the rounded look it has in growth form. Please and thankyou. Would love to be able to make a Japanese garden with a bamboo wall around it.
