23: Mandala Tower

Posted on Nov 7, 2012 by in 1728

The entire site has been updated! More on this below.

The November contest, is to make a tall architectural masterpiece with a maximum of 1728 Zen Magnets. The building must be at least three times higher than it is wide at the base. No additional structural objects besides magnets may be used, however building on a magnetic surface is allowed (and actually recommended for stability.) The structure does not need to be solid. And the base of the building is measured at the widest points touching the ground. You’ll need to submit two photos: One of your actual submission, and one to show your building is higher than the 3:1 proportion.

Zen Magnets only for this contest. If you don’t have Zen Magnets, hold tight, more contests will soon be held at A limit of 1728 magnets to be used. If you don’t have thousands of magnets, you’ll have to especially focus on the lighting, framing, and photographic integrity.

Though this is a skyline, your mission is to build only one building.

As usual, the judges will be your peers. So don’t aim simply to make the most amazing sculpture, try to take the most beautiful photo. There will be at least six winners, and possibly more depending on participation. The prize for first place will be $100 Zen Credit. Zen Magnets only in this contest. Again, this is a photography contest as much as a magnet sphere contest. Everything you submit goes into the public domain. Having fun is the most important requirement. Submission deadline is the end of November.

To enter, load your two full resolution photos on to, and fill out this submission form:

Contest Weblog Update:

Sorry for the week and a half contest outage. We sorta had to start all over, but the rebuilding resulted in an upgrade. For those who are interested in technical details: We have recently activated on Cloudflare, a cloud caching network which would allow to respond faster, and be more enduring under extremely high traffic. However, the DNS forwarding implemented by Cloudflare seemed to have unhinged the SQL database of our contest wordpress site. And when we tried to recover the database, we ended up overwriting it and breaking the old contest site entirely.

Fortunately, google had old copies of our contest site that we were able to refer to when building the new contest site. The weblog is now much cleaner, more visually compelling, and is also optimized for viewing on tablets and phones via When the full frame site is viewed on a desktop, search and other navigational options are also available.
