best “free” online 3d graphic design software?

Hi i mainly want to use it for level editing, landscape and game production?

Screen rotation, downloading and wifi on Dell Axim X5 Pocket PC?

So, I’ve recently found this little PDA or Palm Pilot thing, (Whatever you want to call it) called the Dell Axim X5 in my closet. I turned it on, and it had never been used before. I think that it’s a really cool device, but there are a few flaws. I’d like to be able to browse the Internet without having to actually physically attach the device to my computer, to be able to download and I’d like there to be a screen rotation feature. So, I know that there is a wifi card that you attach to it to get wifi, (Since it doesn’t have it built in) but is there some kind of free Internet software that adds wifi to your device? Second of all, I’d like to know how to download. If I want to put on, say a theme, would I visit the site that has the theme that I want on my computer and download it to my Pocket PC, or would I visit the site straight from my Pocket PC? Could I please have detailed instructions on how to download please? Thanks! And last of all, I’d like to know how to rotate the screen into landscape mode. (My device doesn’t have a built in accelerometer by the way) I’m either running Windows Mobile 2002, or Windows Mobile 2003, but I know that I’m not running Windows Mobile 2003 SE, and 2003 SE was the first to feature screen rotation. So is there any free program online that rotates your screen for you? Thanks in advance!

By the way, here’s my device’s information: Dell Axim X5 running either Windows Mobile 2002 or Windows Mobile 2003.

How can I make a single picture out of multiple ones of the same landscape view?

I have several overlapping pictures of different parts of a same landscape. I would like to make a larger picture encompassing the whole view.

I am looking for some software or online tool that can do this. There must be one because my camera has a mode for producing overlapping pictures for that end (I don’t have its accompanying software with me).

I am looking preferably for an automatic way of doing this, rather than having to do it by hand on Photoshop or similar programs.

I am aware of the Microsoft Photosynth’s new tool but that is not what I want since it does not produce a regular, normal picture.

It would be nice to have a free tool for that, but if there is no such thing, one that is not horribly expensive will do, too.

Thanks!
I don’t think this is exactly like a collage. I think it is called stitching.

I found a very good, free solution at http://www.autostitch.net/ . It points to more advanced, commercial products there as well.

Also, it seems that Photoshop CS3 does it very easily with auto align and auto blend commands (see http://www.freemacphoto.com/panoramas-with-photoshop-cs3/).

Thanks!
