Morphing Street Skyscraper - (Speaking > Unusual Situation)

You are walking down a busy street when you notice a building that seems to be changing its shape and appearance every few minutes. The structure morphs from a sleek skyscraper to a medieval castle, then to a futuristic dome.

Call a friend and describe this unusual situation. Explain what you're seeing, your thoughts on how this might be possible, and ask if they would like to come see it with you.
