The marbles replace the fingers pushing the buttons of the Lego version. The marbles will propagate the bit flow to the next logic gates. In the middle you can see the XOR-AND mechanical combination as known from the Lego version which does the logic. The marbles flowing into the input are "lost", like in a real logic circuit. And new marbles are released at the bottom depending on the logic decision. == Copper Model == <gallery caption="Prototype" perrow="5"> Image:IMG_0367.JPG Image:IMG_0368.JPG Image:IMG_0383.JPG Image:IMG_0385.JPG Image:DSC00005.JPG Image:DSC00006.JPG Image:DSC00020.JPG </gallery> <gallery caption="Production"> Image:DSC00011.JPG Image:DSC00012.JPG Image:DSC00019.JPG Image:DSC00010.JPG Image:DSC00021.JPG Image:DSC00027.JPG Image:DSC00028.JPG </gallery> <gallery caption="Final Model"> Image:DSC00009.JPG Image:DSC00008.JPG Image:DSC00007.JPG Image:DSC00010.JPG </gallery> {{#ev:youtube|idsxMMD5uRE}} == Photos == <gallery caption="bend-a-thon"> File:IMG_1310.JPG File:IMG_1311.JPG File:IMG_1312.JPG File:IMG_1313.JPG File:IMG_1316.JPG File:IMG_1317.JPG File:IMG_1318.JPG File:IMG_1319.JPG File:IMG_1320.JPG File:IMG_1321.JPG File:IMG_1322.JPG File:IMG_1323.JPG File:IMG_1325.JPG File:IMG_1327.JPG File:IMG_1329.JPG File:IMG_1339.JPG File:IMG_1341.JPG File:IMG_1342.JPG File:IMG_1344.JPG File:IMG_1345.JPG File:IMG_1347.JPG File:IMG_1348.JPG File:IMG_1350.JPG File:IMG_1351.JPG File:IMG_1352.JPG File:IMG_1353.JPG File:IMG_1354.JPG File:IMG_1355.JPG File:IMG_1356.JPG File:IMG_1357.JPG File:IMG_1358.JPG File:IMG_1359.JPG File:IMG_1360.JPG File:IMG_1362.JPG File:IMG_1364.JPG File:IMG_1365.JPG File:IMG_1367.JPG File:IMG_1368.JPG File:IMG_1369.JPG File:IMG_1370.JPG File:IMG_1371.JPG File:IMG_1372.JPG File:IMG_1374.JPG File:IMG_1375.JPG File:IMG_1378.JPG File:IMG_1379.JPG File:IMG_1380.JPG File:IMG_1381.JPG File:IMG_1382.JPG File:IMG_1383.JPG File:IMG_1384.JPG File:IMG_1385.JPG File:IMG_1386.JPG File:IMG_1401.JPG File:IMG_1402.JPG File:IMG_1404.JPG File:IMG_1412.JPG File:IMG_1413.JPG File:IMG_1416.JPG File:IMG_1429.JPG </gallery> <gallery caption="Science Festival"> File:SF_2011_0.JPG File:SF_2011_1.JPG File:SF_2011_2.JPG File:SF_2011_3.JPG File:SF_2011_4.JPG File:SF_2011_5.JPG File:SF_2011_6.JPG File:SF_2011_7.JPG File:SF_2011_8.JPG File:SF_2011_9.JPG File:SF_2011_10.JPG File:SF_2011_11.JPG File:SF_2011_12.JPG </gallery> Box built http://lh6.googleusercontent.com/-U-IhZsPSwto/Trm0ij7XiII/AAAAAAAAAGA/LA_l5STm0_4/s640/11%2B-%2B1.jpg Ready for shipping http://lh4.googleusercontent.com/-DIJfsUT9HK0/TrnBMTB2GAI/AAAAAAAAAGQ/n8LsA6JFfuk/s640/11%2B-%2B1.jpg Artist's view http://lh4.googleusercontent.com/-C1EaWXqvyZo/Trv8p4NRnxI/AAAAAAAAAGg/dOz74_qZxHA/s500/11%2B-%2B1.jpg == Videos == {| class="wikitable" |- | Almost finished: first calculation ever.
