This new Litracon based lamp consists of four identical pieces of concrete. Due to special geometry, these pieces form a stable structure without fixing them together. Now you can make your own lamp by using concrete blocks and a lightbulb in the middle. Litracon is normal concrete but with thousands of parallel optical fibres embedded into it.The fibres can pass the light and color through the block .You can get this lamp for $770 plus the shipping taxes from Hungary. Ingenious no?
