Lego is clearly an artistic medium. But apparently it can also be an artistic subject! As illustrated by painter and occasional AFOL
Lester Murphy (aka
Lenny Hoffman aka
Glencaer) in these wonderfully vibrant expressionist interpretations of his favorite Lego bricks...

Above, we have the indomitable
headlight brick, one of the earliest SNOT-enabling bricks. Even though the newer and easier to use
87087 brick is starting to replace it these days, the headlight still retains a certain charm and utility (for example, a pair of these can be used to do some very small-scale SNOT-180). Heh, listen to me, waxing lyrical about a frikking Lego brick!

And here are some of treatments of another incredibly useful brick, that carries the now legendary title of
Travis brick or
TK brick, named after Lester's friend Travis Kunce (sadly no longer with us) who loved this brick so much he got a tattoo of it!
I think these paintings would look great on the wall of any Lego fanatic's workshop...
