Just to show I'm not totally closed-minded, I want to point out that I have no problem at all with this sculpture of a giant blue bear peering into the Denver Convention Center entitled "I See What You Mean." In fact, it doesn't seem to strike sparks like the horse does - I don't think I've heard anyone say they didn't like it. IIRC the artist made a batch of small scale models of this that were hot sellers at the Democratic National Convention here last summer.
I can't exactly put my finger on why I feel so differently about the two pieces. I'd be interested to hear how you feel about them.
As long as we are on the subject of art at DIA, this rather strange mural inside the main terminal has set off a whole series of conjectures of how it is linked to secret Masonic symbolism, the New World Order, or the extraterrestrial aliens that are purported to live in subterranean chambers under the airport. Some apparently refer to DIA as "Area 52." The NY Times article alludes to this, but the best rundown I've seen appeared in the local weekly Westword a while back.
Frankly, "Dream of Peace" is rather peculiar and if you travel through DIA I'd recommend you take a look at it.
