I love to see all the different creative ways that people come up with to make LEGO mosaics. I heard someone joke about how he was going to show up to BrickCon with a mosaic made entirely out of LEGO tires, and I thought that might not be a bad idea at all.
I see that DJ Baggadonuts has come up with several interesting mosaic techniques. One of them is to stack headlight bricks into columns, and then stick jewels into the holes. Light will shine through from the back of the mosaic, creating an interesting effect. If the backlight is strong enough, it will light up, "sort of like a LEGO LiteBrite," as Mr. Baggadonuts says in his blog. (The blog archive is worth a look; in it you can find links to all sorts of entries explaining how he accomplishes his different mosaics.)
Here are two examples of this jewels-inserted-into-headlight bricks technique:
The stability of the mosaics can cause a problem, as they are made of columns of headlight bricks and have very little cross-bracing (which only occurs in the black sections). But with persistence, it can be done.
Mr. Baggadonuts has several other interesting techniques that I would like to cover in future posts. ;-)
(Yes, yes, I love to use smileys. I can't help it! Everything seems so very serious without them. ;-) )
