Ah I forgot about arbitrary limitations like that. Here's mine:

I have a new favorite operation, it's the no-collision, no-sync, bond grower. You take a track 

——- Q —– E —– E —–>

        B1      B2    .. .. …

Where:

Q is +Bond instruction

E is a grab/drop instruction

B is the Bonding symbols from the factory. Q and E take place on the bonders, I just can't draw it that way without paint.

If nothing is in this area, the first pass will drop the atom at B2, the second pass will bond the atom to that at B2, shift one to the right and drop it. This way, you never get collisions because the bond operation makes everything move together. You don't need syncs and the other waldo can interact nicely with this by optionally grabbing and rotating, or grabbing and ferrying product to the outputs, etc. I know some people have really gotten cute with inline bonder operations, but I've been slow on the uptake because they can take a lot of time and fiddling to get just right.

Here's a pretty thing.

It's amazing to me how I'll find some fast and efficient solutions very quickly, while some problems take me ages to get the clunkiest and most miserable hacks to work. Sometimes the brain no worky so good.

That's a beautiful machine, Helmut. So elegant in its simplicity. With a molecule that large, managing it any other way would be a nightmare! I can only imagine what sort of hideous contraption I'd build.

No, I don't own it. I played the demo and adored it, though I'm not sure my brain is wired to ever get past the early levels. I liked the planning and visualization aspects. SpaceChem (and Auditorium) are both very hypnotic. If I owned it, I'd have to bring it to work, and if I brought it to work I'd play it, and... you get the picture.

But I was hugely impressed by the way it teaches you to think.

This is a weird level. Sometimes it's what you just avoid doing that gets the job done.Instead of making a bunch of complicated dis-assemblers for the varied input chemicals, I stripped off the easy Carbon and tossed the rest in the trash, which is made up of that great long pipe that leads to nowhere. Some levels you need to use every atom in order to keep the factories balanced, but not here. Granted some people have to live in and among some sludgy Carbon pools and the temps just keep rising on planet, but that's the price for progress.

I have 2 missions left on planet 6, Hephaestus IV. 3 more planets after this one. The thing about this game is to just let it simmer on the brain. The only way I've found to enjoy it is to drop in every day or two, fiddle with a couple attempts at progress, then leave and let it soak in the subconcious for a while. It's really hard to sit down and 'play' it. I also suspect it's a little bit hard to restart once you've let it sit for a while. I have looked at some of the other vids suggested by youtube while posting my solutions and I think that's a good way to poach some new ideas and get a little enthusiasm going.  Unfortunately, it's almost the only thing that will run on my 7900GS, which is the h/w recovery and withdrawal prevention card.

Here are some vids from some people who really are at the end of the normal curve.

Just for those who might be curious, brainfuck is a programming language developed for the amusement of programmers. I thought SpaceChem was really just playing with a language interpreter and that is somewhat true, albeit a very simple one.

I sorta like the idea of playing with these languages, I'm certain they would help my ordinary everyday programming and foster greater creativity and joy in life and almost positively increase my sexual enjoyment, but yeesh.
