It's Genuary time again! Today's prompt is "One color, one shape". I chose to make a hepta of heptagons made from blue heptagons.

Prior to October, I'd taken little interest in the property's location or #terrain due to cost. Those features swelled in importance as I #contemplated its' use for a small business #HQ. Few if any photos at the other #clinx reviewed presented the landscape in front of the #Heptagon

A few photos of the level backlot showed towering walls of vegetation surrounding a sandy area around a pool & cactus garden with barely enough room to squeeze in another cozy cabin. Google maps' 2D satellite image showed the adjacent public lands & roads

Google Earth allowed me to view 34.251 ~ 118.266... in 3D from multiple positions above. The #compound reminded me of Myst Island with its' unique unusual structures possessing fantastic interiors of #hand-crafted natural materials you must feel/touch

Here are some works inspired by the #Myst franchise posted at #DeviantArt
