[ WP ] a cave man travels to the year 2060 . There 's a new display in a museum and he sees it 's him .

Gronk could n't keep his eyes off the shiny crystal held by the frozen man at the back of the cave. The man held it out to him as if it was an offering. 
 He took a step closer. The crystal began to pulse. With each flash it changed color. Red. Green. Blue. 
 Red. Green. Blue. 
 The glow lit up the drawings on the cave walls around him. 
 Cautiously, he took a step back. The crystal dimmed. 
 Gronk let out a squeal and quickly stepped forward again. 
 It brightened and flashed faster matching the throb inside his chest. 
 Gronk smiled. 
 
 By the time he got close enough to grab it, the crystal was changing so fast the colors merged into one bright white light. 
 Shielding his eyes, Gronk snatched it from the man's hands. 
 
 FLASH! 
 
 When he opened his eyes, Gronk found he was in a different cave. This cave was n't like any cave he had been in before. Everything was smooth and angled. The flat floor felt strange against his feet. In front of him was a man inside a strange rock. The man had a frightened look on his face. 
 
 The rock between them was hard to the touch but he could see through it like water. He thought it might be ice at first but when he touched it, it was n't cold. 
 
 When Gronk looked at the rock, he could see the face of another man looking back at him. Gronk reached up to touch the man's face. When he did, the other man reached up too. Gronk realized it was his own face, just like when he saw it when looking into a pond. The rock really was like water. 
 
 Looking back up, Gronk could see that the man in the case had the same face as the one in the water rock. It dawned on him that both faces were his. 
 
 Gronk shrieked loudly. How had this shaman stolen his face? 
 
 Then Gronk noticed something pulsing in the shaman's hands. The shaman was holding the crystal from the cave! 
 
 Gronk growled. That crystal was his! He reached out to grab it but his fist hit the clear rock between them, cracking it. He smashed the rock with both fists breaking it to pieces. 
 
 Gronk grabbed the crystal from the shaman. 
 
 FLASH! 
 
 Gronk was back in the painted cave holding the crystal in front of him like an offering. The crystal was n't pretty anymore. Just a dull black. He tried to step forward but could n't move. 
 
 The crystal began to glow a little. In the faint light, he saw someone coming towards him in the cave. As it flashed brighter and brighter, he noticed the man coming towards him was the shaman with his face. 
 
 He tried to shriek but he was frozen stiff.
