In a bowl, dissolve one package of gelatin in 1 cup boiling water. Add 1/2 cup cold water; stir. Spoon half into an oiled 10-inch fluted tube pan. Chill until almost set, about 40 minutes. Cool the other half of gelatin mixture; pour into a blender. Add one cube of cream cheese and blend until smooth. Spoon over the first layer. Chill until set. Repeat five times, alternating plain gelatin layer with creamed gelatin layer, and chilling between each step. Just before serving unmold onto a serving platter.
