check out www.blambot.com, Nate has some free sci-fi-ish fonts there you might like.
Look at Android Nation, Mars Police, Mother Ship or Botix.
One note tho, you probably want to check with Nate himself before you use any of these fonts for this purpose.

true, mostly these are meant for people making their own comics, so that's why i say contact Nate Piekos before using one of these fonts for your projet.

Read EULA here. I guess you should be fine if you are a non-profit, if not you might hafta use *gasp* Comic Sans ha ha!

Thanks for the info. Yeah, I saw the agreement and I 'm not too into any of the fonts, so I am still looking.

What about www.fontdiner.com?

"retro-futuristic" that's all i could think of outside of the suggestions i already made.

These are perhaps more contemporary than futuristic, but some ideas:

(I believe these are all free, at least for non-profits...)

Saturn Return (an OCR face)
Train in Vain (a rounded sans)
Mr H Anton
Indivisible (my favorite of the freebies...but I have yet to find a project for it)

I knew a designer once who always showed his clients a diagram with the three words "good, fast, cheap" on it. When negotiating contracts, he would tell them that they could pick two (i.e., they could have their project done good and fast, but then it couldn't be cheap).

I remembered this when I saw your post's title, Alberto, saying that you want a font that is " free, fun, [and] slightly futuristic."

>Hey Dan, I know that quote. I think my request is a little easier to fulfill. : ) At any rate I am going to probably use a face I already have. > >

Do you know which one? I've never been quite sure how to choose type for kids, and I'd be interested if you can shed some light on this. My gut feeling is that people tend to "talk down" to kids and choose dopey faces that seem to them, as adults, to have qualities they read as "childlike" and "fun." The educators at our museum, at least, seem always to favor "lively" faces that move perilously toward the comic sans end of the spectrum. Whereas the best designing for kids I've seen is in trade book publishing, where the faces seem in general much more sophisticated. I suppose one gets paranoid about coming off as boring. What do you think?

My point was just to illustrate that you would find a better fun and futuristic font if you were to buy one, instead of look for a free one.

make sure you read the EULA ... it is very specific about when you CAN and CANNOT use them for free.

You might check out http://www.point-central.com/

fontdiner is also listed on point-central, as is astigmatic and many other great foundries that offer brilliant and fun faces.

Amelia! Ok, maybe it's retro-futuristic.

I'm going to make a sign of that Dan. I remember that from years ago and had forgotten about it.
