Discover the calming power of the flow state with inspiration from the coral reef. Jigsaw puzzles give us an easy way to get into the flow, which is one of the reasons why they have boomed so dramatically in recent years. With Reef Dream, the second of her 1000-piece Flow puzzles, Elin Svensson uses harmonious colour gradients to captivate the puzzler, and take them on a gentle journey to a place of calm.
