An Invisible Force is a beautifully crafted desk which answers questions.
You selects a question you want answered from the packs of question cards (“Will my love be returned?” “Do I have ennemies?”, etc.), insert it in the slot on the table, and hold it down until the end of the answer. The answer is gradually spelt out on the desk itself which surface is laser-cut into a grid (like the pixel on a computer screen). But there’s a metal plate under your hand that heats up, so you’re forced to endure pain if you want to know the answer.
