Trim the ends off the rhubarb and slice into relatively small slices. Put the rhubarb, sugar and orange juice in a small pan and stir gently to dissolve the sugar. Bring to a low simmer and cook a couple minutes until the rhubarb softens. Try not to stir much as it softens to avoid breaking up the rhubarb.

Set the rhubarb aside to cool.

Put the cream and yogurt in a bowl and beat until relatively stiff peaks form.

Set aside a couple pieces of rhubarb to decorate the top of the glasses and fold the rest into the cream mixture. Divide the mixture between two glasses and top with the reserved rhubarb. Chill until ready to serve.
