Bizarre Mini Piano Calculator Calculates Sums with Notes

There are many things in this world that are hard to fathom, this bizarre Piano Calculator being one of them, another being that I’ve just spend the best part of twenty minutes stenciling out the above image from the original (annoying) background featured in the product shot in order to feature it here – still, as a curiosity, it’s worth a brief mention simply because we don’t doubt that this particular calculator will prove extremely annoying after even a few minutes of use.

Yes, you’ve guessed it (clever you) this Piano Calculator does indeed play a note with every key press as you try to calculate your monthly outgoings is as tuneful a fashion as possible.

Great for really annoying your office colleagues (especially if you happen to work in a finance department) the eight digit Piano Calculator comes in a choice of white, blue, black and pink, is powered by two AA batteries and, we’ve heard a rumour that the Aphex Twin has apparently decided to compose his entire next album using one (well, ok, that’s probably not true).

The Piano Calculator retails for ¥1000, which is approximately $9 / £4 / €6.
