We've featured some neat coloring books and apps around here, but this will be the first scratchboard art we've ever written about. Lago's "Scratch Night View" is a series of scratchboards based on cities around the world. With each one, you simply scratch off the grey-colored sketch as you please, revealing a lovely golden color below. The process is quite calming and the results are frame-worthy:

So far, they've focused mainly on places in Europe, Asia, and the United States. The individual scratchboards can be purchased à la carte:

• Paris (portrait) ($15)
• Paris (landscape) ($14)
• London ($15)
• Berlin ($15)
• Cologne ($11)
• Florence ($12)
• Hamburg ($12)
• Seoul ($14)
• Singapore ($10)
• New York City ($15)
• Las Vegas ($15)

...or you can get collections of them in book form:

• Classic Collection (London / Hamburg / Budapest / Florence / Blank page) — $22
• Vol. 2 Asia (Singapore / Seoul / Tokyo / Hong Kong / Blank page) — $22

Each item comes with a white plastic scratch stick, but if you really want the best experience, I say get the company's handsome scratch pen/stylus, which looks way cooler and isn't as likely to break on you.
