Hmmm, well I started my plan to build an original version of the Cosmic Fleet Voyager in black with transparent dark blue lights...but hit a bit of a snag on several cosmetic bits I was missing. So...rather than just skip over them completely I decided to place some orders!

It actually took 6 orders total, spent about $50 in all, the main highlights can be seen here:

Unfortunately there are no black 1x2 bricks with a left facing arrow...but there are ones with downward facing arrows! So I got those.
The other bad spot was that there are no 4x10 transparent dark blue plates, only 4x8 ones, so I'll have to make due with those.
There's also no black 1x2 decorated tiles with the old school computer pattern on them, so I figure I'll just use one of the modern ones in their place.
Found some other neat stuff too while I was browsing, like those decorated transparent purple radar dishes. I'm going to use Brasso on them to take off the pattern and then I can have one more thing to add to small, but growing baggie of transparent purple stuffs! Speaking of which, if you're not aware, Lego ~finally~ came out with a transparent purple windscreen!

Nifty!

I also got a bunch of those silver and copper circular pattern tiles, which I was thinking I'll use for a holodeck type room, having them on the floor, walls and ceiling (not sure how I'm going to pull that off yet)...but I need to get a lot more, obviously. I've already got about 30 of them so it was nice stumbling across a little horde for sale with the new stuff I was looking for.
Got a couple more sets of medium blue doors too, the ones I was talking about using in the medical bay.
That transparent green computer screen is also really cool, never seen that before, although I was ~sorta~ hoping I would stumble across one of these in transparent dark blue:

I've already got one in transparent red:

Those are the only two colors they come in.
That glow-in-the-dark lightsaber blade is also quite interesting. Seems here lately there's been a whole slew of new transparent colors for them, including purple, light purple, dark pink, bright green and glow-in-the-dark. I just checked and the glow-in-the-dark one was the only one I was missing. It's fun completing color collections! ^__^
