A wiki for Geomag enthusiasts!
So... it's been a while since I made a post here.

Since my last post, I discovered that there's a cool place for Geomag enthusiasts to make interesting posts: the Geomag Wiki hosted by Wikia. I'm PolyClare over there, for multiple obvious reasons. ;)

I don't really know what the best place to post Geomag stuff is. I know I'll keep posting occasional stuff on the Geomag Wiki. Maybe I'll start up again and post more here on toymags, or maybe I'll hang with the Geomag crowd on Flickr. There's also a Polyhedra crowd on Flickr. Maybe I'll hang out on some mystery combination of all of these; we'll see.

Anyway, it was time to spread the word here 'bout what sorts of stuff is out there for those with Geomag proclivities. Enjoy!

In the meantime, my Geomag collection has grown to slightly scary proportions[*]. Boy am I enjoying that!! :D



[*] Since my last post here, Magnetic World has folded, and much of their stuff is being unloaded on eBay. Many bits of which found their way, somehow, into my collection.... ;)

Boring inventory post. Future acquisition possibilities.
So I've gotten quite re-energized about playing with my Geomags again. I made a recent post of some of the polyhedra that I built, and after that post I bought some more Geomags and built a bit more. Then Saturday evening it was time to pull them all apart (so I could access the space the polyhedra were taking), and I figured it was a good time to take inventory so that if/when I (obsessively) buy more Geomags &/or more Geopanels I will be sure to buy the most appropriate sort.

Boring Geomags & Geopanels InventoryCollapse )I'm entranced by the pretty colors of the Glow Panels, but they're hard to get (I've ordered them from the UK on eBay). Plus for the sorts of polyhedra I favor, you really often need 12 pentagons, and the little 60-piece Glow Panels sets (I bought two on eBay) give you only one fluorescent yellow pentagon per box. I really like the pink and light blue panels in those sets quite a lot. I'm also tempted by the colors of the new Pastelles sets with Panels), but the Pastelles with Panels seem also to be non-USA. But they have such lovely lavender rods. I'm also tempted by the Blaze sets (also apparently non-USA) containing black and orange rods. I don't especially desire the orange rods, but having some black would be fabulous! It's also possible to order sets of panels individually, in the classic colors (non-glow) plus clear transparent panels.

It's pretty obvious that I need at least a few more green bars.

Hmmm. Decisions. I've gotten into the whole quantity and color thing because I really like making multiple models *simultaneously* with interesting variations, with colors chosen carefully to highlight the symmetries and variations appropriately. And I enjoy having an extensive collection I can bring to a party for fun group play! OK, I still haven't done the party idea, but I will!

I really wish the Geomag people would make some hexagonal panels! Making hexagons from three diamond panels just isn't nearly as stable as I'd like. And hexagons come up a lot in my constructions. Oh well.

UPDATE 1: Wow, a Magnetic World person commented here about cool new Geomag Premium sets, and more USA availability.

UPDATE 2: I added a list of Grand Totals to my inventory above. Phew!

UPDATE 3: Discovering that the individual sets of single shape/color panels were being discontinued, I placed an order for a bunch of them, to fill out my collection of panels in "classic colors", plus extra clears. panel order hereCollapse ) I expect to order more Glow Panel sets later (when they become available in Feb. at Magnetic World), and maybe some fine new Geomag Premiums. And a set of green bars to make the green bars at least a little useful.

Back to Geomags, finally!
So, after setting up this community aeons ago, I finally had enough vacation and mellow time that I pulled out my Geomags and started playing. I made several constructions, pulled 'em apart, made a few more, and finally pulled out the camera to capture the last ones. I'm re-inspired! I've even ordered a few more Geomag sets (can't help myself!).

Here are some pix (click for enlargement and annotation):

A link tangent
Not a magnetic tool, but still one of my favorite polyhedra construction kits:

On R. Buckminster Fuller's ideas, here is an online version of A Fuller Explanation: The Synergetic Geometry of R. Buckminster Fuller by Amy C. Edmondson.

For starters, a little geodesic dome (freestanding)
I took pics, along with a little Lego guy to give a sense of scale. Small pics behind the cut, with links to full-size pics.

The Cut!Collapse )

Musings on rigidity, the d30, a.k.a. Rhombic Triacontahedron, and the Buckyball / Soccerball
Inspired by a comment I made elsewhere.

The talk of rigidity is very important in these toymag structures. Only triangles are rigid. I believe the rigid triangle is the basis for much of Buckminster Fuller's work -- I intend to read a lot more about his work here (looks so fascinating!). So any structures with faces that are nontriangular will need bracing of some sort -- either enough crossbars to turn the face into a series of trianges, or with structures build on those faces consisting of triangles, or with a solid face (like the "panels" available for Geomags).

Rhombic Triacondahedron otherbill wrote: The d30 is an interesting structure.

Oh, this object is perhaps my favorite polyhedron! It's the rhombic triacontahedron. I've gone on about it in two recent posts in my LJ (here and here). more details behind this cutCollapse )

Funny that otherbill mentioned the soccerball / buckyball / 32-sided object. Its "math name" is truncated icosahedron. On New Year's Eve, I brought my Geomags to the party I went to. I was rebuilding that augmented dodecahedron I mentioned above, when the guy who threw the party asked me to make a buckyball instead. and more details behind this cutCollapse )

Pictures soon... Real Soon Now....

Welcome to the new Geomag/Supermag community!
Supermags (eBay pic) I recently ordered 102 piece multicolor set from Sharper Image via eBay for $14.95, $22.13 including tax and shipping.

If anyone has suggestions or tips for great prices on Geomags or Supermags, please share them.

I plan to post some pretty pix of colorful polyhedra I've created, Real Soon Now. If anyone else wants to post pix of polyhedra, or any other fabulous structures they've made, feel free!

OK, there's a start for this new little community. Welcome!
