The videos of this site is recorded in a multifunction "platform". This "platform" have the function of being my bed at night, my sofa in daytime, my computer desk, my reading seat, lunch table, workplace and video taking area, etc. It's so important for my daily life.

The videos are taken my hanging a webcam horizontally over the table as shown. We also need two usb lamps to illuminate the background. There are a total of 20 LEDs on these lamps, so it is comparable to a surgerical lamp, I wish. (Did you find any shadow of my hand in the videos?) The drawings are done on A4 papers placed on a hard file that covers the keyboard of the notebook computers. 

The table, the cam, the usb lamps, the computer and also the whole table can be disassembled and moved away to give me a sleeping place at night. You may think it is like a dog's house, but it bears a lot of values to me, really.
