There are paintings and sculptures that tug at the heart because they catch a simple moment and make beauty conscious. There is music that "brims the eyes with bliss". Such works of art are shock waves that travel between the ego and the Divine Guest, reminding us of a nobler purpose to life. They create moments in which we know that we can lead a symbolic life, when the Self, like Michelangelo's God, reaches out to touch the outstretched hand of our inner Adam and our ego.
Every moment in life is a prayer, or could be. I think you can pray yourself into the mystery of the moment, or allow for the blessings of the moment to sustain you. Every moment is an invitation, and whatever you do in that moment, if it's dedicated to God, then it is a prayer.
