I just found this on another forum, I'm can see I'm going to spend quite a few hours on it after work. I stopped on the second machine just now because it was too much fun.

yes that is the best.... so addictive just have to play with music down or muted though, there is another one thats not so cartoonish... buggered if i can remember what it is called... saved to favorites on my other pc, real engi-nerd stuff... i'll send it to you pat when i find it.
Ooh.. thanks Pat.. I think my boss is going to want to have a word with you soon..
I'm stuck on mission to mars at the moment.. Tricky stuff!
People on the other forum mentioned this Mission to Mars too, I'm looking forward to it. Can my engineering degree and eight years working as an engineer prove an advantage?
Thanks for the link, will check it out when at home 
This one tickled my nerdy engineering bone for quite some time:

Had a really productive afternoon at work - Now I'm stuck on "four balls". The steam-locomotive method doesn't seem to work the way I've done it, so I think I'll try a more paddle-steamer approach..
My favorite so far is 'up the stairs' (at least I think that's what it was called! too many machines since then!) where you have to get up a flight of stairs while little balls get in the way and stuff up your machine.
It's all a bit like scrapheap challenge only without the welding and grinding..
OK Mr engineer swotty dude, explain to me how women volleyballers 'costumes' (if you cant fit the word 'costume' in pt 10 font on the item can it be called such?) stay in place?
Surely it must be some kind of advanced nano technology or even an anti-gravity drive modified to become an baconstrip super magnet?
I'm not sure, but I did read an article on these uniforms not long ago, apparently they are engineered to keep the athletes cool in warm playing conditions. The story is in the photo captions:

What level u guys up2!? i'm a lil stuck on one atm, but I'm off to bed. 8 hr PD and woot woot =] BEST day ever. 
that stair one is a pain in the arse it would be easy if u didnt have all those damn balls dropping everywhere. in four balls do u have to get all four in

This method has worked up to here.
(Ps, new photo upload works nicely).
Lol, you wont believe what Im studying. And this is all i can think up. Haha.
FantasticContraption.com/?designId=397777 . Thats how i solved mission to mars. Don't look if you don't want to know.
FantasticContraption.com/?designId=398007 And stairway. Hehehe i love this game. Again, don't look if you don't want to know.
haha, I think I may be the one who posted it on the other forum greenpat got it off. Its a dangerous timesink.
The simplest answer I could come up with for 'four balls' FantasticContraption.com/?designId=405626
omg, type in random numbers to designs and you get to see some real effort people have put in, funny when it takes you 1 minute to make something sly to do the same thing
