Since some of you seem to enjoy these tessellation experiments, here's an old projection mapping installation project of mine for which I combined similar patterns with digital fabrication (laser cutting & cutting plotters) to produce two Victorian-style room dividers with 620 handfolded paper cones, which were then used as 3D projection surface. Visitors could use an iPad app, housed in a small dolly table (also laser cut), to produce custom animated patterns which were then project…

Autonomous programmable microscopic electronic lablets optimized with digital control
Lablets are autonomous microscopic particles with programmable CMOS electronics that can control electrokinetic phenomena and electrochemical reactions in solution via actuator and sensor microelectrodes. In this paper, we describe the design and fabrication of optimized singulated lablets (CMOS3) with dimensions 140x140x50 micrometers carrying an integrated coplanar encapsulated supercapacitor as a rechargeable power supply. The lablets are designed to allow docking to one another or to a smar…

To get a stethoscope into Gaza you needed to buy a TV:
Resisting the blockade in Gaza with Mohammed Abu Matar from Tashkeel3D.
"I met Mohammad in 2018 while interning at a digital fabrication lab in Amman, Jordan. It was late afternoon, and the lab was almost deserted. Two men were playfully experimenting with the laser cutter, trying to figure out how it worked while sharing a moment of fun.
"Intrigued, I approached them to see if they needed any help figuring it out. They seemed to have navigated their way around the tool, so we started chatting.
"I couldn't help but stare at an orange plastic object in front of them. It had a central Y-shaped component with a transparent, flexible tube hanging from its tail, and a circular plastic piece attached to it. They handed me two rubber earbuds to fix on each end of the Y-shaped piece: it was a stethoscope, with some parts 3D-printed, and others bought and assembled.
"Mohammad and his friend were in transit in Amman awaiting a Canadian visa. Their team was invited to attend a conference to showcase their work on manufacturing open-source medical hardware in Gaza. Unfortunately, they were denied a visa to Canada, and so they returned home."
“Why not just buy stethoscopes?” I asked. Mohammed explained that first of all, bringing stethoscopes into Gaza was often impossible because the Israeli occupation arbitrary restricts entry of aid claiming they are dual-use goods. Second, buying stethoscopes in large quantities wasn’t feasible as they are expensive.
For emphasis, the Israeli occupation bans many essential and life-saving medical equipment under the dual-use goods claim. These restrictions began with the land-air-sea blockade on Gaza in 2007.
