Create an aesthetic collage revolving around the concept of a 'Bisson board'. The image should include pieces representing the game, like a detailed game board with blue and white checkered squares, wooden game pieces positioned on the board, and a pair of hands mid-move, to indicate an ongoing game. To form a cohesive pattern, include some abstract elements like geometric shapes, line art, and pastel color blocks. The collage should look harmonious and visually appealing, marrying the elements of art and the strategic delightfulness of the 'Bisson board' game.
