According to http://en.wikipedia.org/wiki/Bamboo, Bamboo Listeni is a tribe of flowering perennial evergreen plants in the grass family; although, the forestry services and departments of many countries where bamboo is utilized as a building material consider bamboo to be a forestry product, and it is specifically harvested as a tree exclusively for the wood it produces, which in many ways is a wood superior in strength and resilience to other natural, fibrous building materials.
Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
Also regular wood glue or gorilla wood glue. You are a carpenter now, keep the wood glue handy.
I happened to have some in my garage. Each plank had the following dimensions: 5/8 inch thick x 3-3/4 inch wide x 37-3/4 inch length. My planks were prefinished which is how they are typically sold. Perhaps you can get some from a friend, a neighbor, or just asking a store if they have a broken box, or discards, or whatever.
Worst case, you can buy "samples" from flooring stores for approximately $5 per plank. Only need two or three planks depending on the profile that you want.
Any sweet board has awesome graphics. Depending on your artistic sensibilities, you can paint your own or just simply apply decals. Both work great if done well. I decided on painting my own and improved my chances of success by printing out the designs on paper and cutting stencils out of them. Using acetate sheets will let you reuse your stencils. Otherwise if you want a single one-off masterpiece just use regular paper or contact paper
