The Fludium was a joint project between Mathmos and Ross Lovegrove.
There were 4 models released - green, yellow, opal and orange. They had matching bases to the wax color, however the opal and orange models were discontinued.
There was a option of a 'color-boosting' bulb for the opal which changed the wax and the base color, however this has been discontinued and it's very hard to find a genuine Mathmos color-boosting bulb.
