Sean just keeps getting better, and while his marbles have always transported you right into the middle of a nebula, this one really takes the cake for being the most chock full of hyper-realistic nebula activity. The colors are incredible. You can see stars being birthed right before your eyes, and you don't believe that this is actually glass, and not an actual slice of space that Sean somehow captured and bottled inside the marble. Truly AMAZING!!! Signed 'SC 2017'.
