Infrared is fun stuff. I've never looked at color infrared images as I've only experimented with it on B&W ages ago but I see the foliage in color infrared still turns out the most drasticl. You can barely see the little tike on the swing in the second image! What's the rig you're using?

This was taken with a modified Canon D60 DSLR. The images really aren't in color. The color is falsely created in post processing. With the visible blocking filter, the majority of the information is in the red channel only, as you would expect, however, with using a custom white balance (usually green), you can set the mapping to that similar to IR BW film, and then by swapping the red and blue channels in photoshop, you can create a blue sky.

Hmm, here are some of mine that I've been bothered to upload to my site...
Not quite as spectacular as EVR's. They are taken with a non-modified Konica Minolta DiMAGE Z10, with an equivilant of a Hoya R72 filter.
As you can see, I don't like to desaturate the pics, instead I just increase the amount of blue until it looks about right...
I find manual focusing very hard for infrared... you can't focus to infinite and expect nice pics... the clearest pics come in at ~1m focus for my cam. Autofocus works sometimes, but can be unreliable.

I have been looking at larger improvised Infrared filters:
Memorex Black 80 minute CDR (Foil/glue chemically stripped)
The cheap telescope body that is beyond repair may be scheduled for retrofit next month. =] grin…
I am curious to see if the grooves embedded in the plastic could have fresnel lens properties at selective wavelengths too.
Anyone tried this yet?
