looking the unique design on wood

[johanbhi]

Hi all

I am thinking of making some wooden storage boxes for my children’s bedroom. I was looking at sliding lid opening but a little unsure how these are made. I saw some examples on this site http://www.customcraftltd.com but couldn’t find any plans.
And give me ideas on the best type, design and thickness of material? Also would these be best glued or screwed together?
Any help will be greatly appreciated
