The Twee FAQ

Q: How can I print?

A: You can save a Twee to the Photos album, then sync your photos and print from iPhoto. If you really like your Twee, you could use Apple's photo printing service inside iPhoto on your Mac! You can also make greeting cards using Apple's free Card app directly on your iPad, iPod, or iPhone.

You can also Mail a Twee to yourself, then save the picture out of email and print from your big computer or laptop.

Q: What is the Educational Value of Geom-e-Twee?

A: Good Question.... We think that Geom-e-Twee can stimulate thinking about the structure of the natural world, matter, and the cosmos, but also to a certain extent how geometry and art interact.

Please contact us if there is anything we can add that would make Geom-e-Twee (or Tree) more valuable in the classroom. Check the EXERCISES section of our website for various challenges.

We understand that there is a national effort in the United States to promote the use of fractals in education. Can we help introduce teachers to Geom-e-Twee? Let us know.

Q 4: Is the Angle the number of Degrees between branches?

A: Yes!

Q 5: What is the Branching Factor or Fan Out?

A: The Branching Factor is simply the number of new branches that sprout from the end of each branch as the tree grows.

Q 6: What is the Common Ratio?

A: The trunk of the tree is divided by the common ratio to get the length of the first set of branches. We keep dividing down the branches to get the length of next "generation" of branches. See the same question in the Geom-e-Tree FAQ for a more detailed answer. This is basically a geometric progression or series, like 1, 1/2, 1/4, 1/8, 1/16, and so on. This is one of the reasons we call it Geom-e-Twee!

Q 7: What is the "Perfect Common Ratio"?

A: The Perfect Common Ratio is the Goldilocks Factor — that is, a Reduction Factor that is not too little, not too big — it's just right, so that the tips of the branches of the tree come up to each other but do not touch.

Note that you can also make branches overlap by widening the angle so that the branches extend over into neighboring territory, but that is because of the angle, not the common ratio. (We also call the common ratio the reduction factor. Same kind of thing.)

Twee has a Gold-e-Locks mode, which is described in the Help.

Q 8: Is Geom-e-Twee limited to 2 and 3 branches?

A: Yes. Note however that Geom-e-TREE can handle geom-e-trees with up to 9 branches. Geom-e-Tree has an 'Arboretum' feature and 40+ themes (including all the themes from Twee). Learn more about Geom-e-Tree on

Q 9: Will there be an Android version of Geom-e-Twee™?

A: There very well may be, as soon as we get Geom-e-Twee for iPad and iPod Touch in the hands of many young people.

Thanks again for reading the Geom-e-Twee FAQ, and thinking about these interesting concepts.
