Need an awesome card for your next special occasion? How about something with moving parts that reveal a surprise photo or image?

While these mechanical iris cards are a little time consuming to assemble, they're definitely worth the effort. The versatile design can be used for everything from adorable baby announcements to party invitations. Create a camera for a picture perfect valentine's day card or a submarine porthole for a steampunk Christmas card - the possibilities are endless.

I love these cards! You could try using iris-calculator.com to get your dimensions, it might help stop the pieces getting caught.
I think everyone is going to get an iris birthday card from now on! Awesome stuff!

You mention running one of these files through a cutter machine? I have one but don't see how they could be used to transfer it to a cutting file? Do you have a pdf that prints the registration marks?

You can use the software that goes with your cutting machine to convert the pdf to the correct type of file. We use Make the Cut which works with many different machines.

Thanks. Looks like I got it all figured out. I'm going to use this to make a Magic 8 Ball box. I think I will modify this with Laser cut wood and brass sheets for the blades.

Do you have a video of the assembly for this? I would like to use it for a project and this one is the best and easiest I have seen.

Great job!

I don't currently have a video for this card, but I'll try to remember to film one the next time I'm putting one of these cards together.

Awesome instructable, and the first one I've made! I used aluminum sheets for mine, but it works just fine:

Did you cut the aluminum with an ex-acto knife?
The blades are actually really thin and I cut then with a scissor from floppy disks' little metal covers. The circles in the outer ring were made out of a thicker aluminum sheet and cut with a cup saw, and the square was cut with a common metal saw.

Thank You. My dream home will have a larger scale version of this iris in it somewhere. I think air powered by a low voltage compressor.

Love it!
I wonder if you want to make a camera, how to use a rubber band to make it ''automatic'' you know you pull the outter ring to close the iris (in this case the camera's diaphragma) it automatically opens again, like taking a photo. Any idea? i want to make for my brother.

This is an awesome idea, and great timing too!
I'm going to try making an Aperture Science version for my brothers birthday (only 2 days away, aaaah!). It will go perfectly with the present, a Portal 2 water bottle from Think Geek.
Thanks for the istructable, I'll post a pic or two here if you like, when (if) I finish it.
If you're interested in a Portal-themed iris, check out my Aperture Science Business Card instructable.
