Much to my chagrin, I encountered this issue this morning when writing
up my own version of word clock... Spans not getting updated after
setting a new style.
+1 expectation that this is a bug

In principle, it ought to be possible to do the whole thing without
swapping and clearing; you should be able to modify styles directly
on existing elements.
Experimenting, I found that I could do this with para's, but not
with span's. I guess this is a bug? Spans are supposed to have a
stroke style, and setting the stroke style on a span works, just not
modifying it.
Maybe you could use a flow full of para's instead of a para full of
span's, for the words. It should look about the same.
Demo of in-place style modification with para's:
Shoes.app do
button "colorize 1" do
@text1.style(:stroke => rgb(rand,rand,rand))
end
button "colorize 2" do
@text2.style(:stroke => rgb(rand,rand,rand))
end
flow do
@text1 = para "First Text"
@text2 = para "Second Text"
end
end
This stopped working when I wrapped the strings in spans and tried
to change the styles on the spans, instead of changing the styles on
the para's.

Thanks for all the answers and suggestions. Due to popular demand,
I've posted my sophomoric Ruby code for Word Clock to the ShoeBox:
http://the-shoebox.org/apps/150
For the Shoes experts reading this, what I *think* I want is an
abstraction where I can pre-generate all the <span> elements, and
use <element>.replace to swap in highlighted and un-highlighted
versions of the text. That seems tantamount to computing things
off-screen, and I haven't figured out how to do that yet.
Enjoy.
