Optical Illusion. Arts And Graphics Assignment, 1992 GCA*, Lucknow, India.
Spiral Big Bang Collapsing On The Outside! Wow!
This is from 1992. It is my submission in Arts And Graphics Subject on the Optical Illusion assignment. If you think this is a good evil eye ward-off, go ahead use it. Ha. Provide attribution but. Nazarpattu?!
Movement Of The Eye
Our brief was 'Movement Of The Eye'. Those were not days of AutoCAD. This was prepared manually on a Card Sheet measuring 71.5cm x 46.5 cm (somewhere between A2 and A1 size sheet). I spent almost 6 days on this from conceptualising and sketching and resketching as I was modifying and evolving and designing and developing, altering etc. on rough tracing sheets to deciding what shall now be done and then finally getting down to drawing it! Compass was used, compass extension was used. I was loving my Geometry! This sounds silly to mention, but never mind. |

Concentric Circles with gradually increasing diameter increase difference!
I began by emanating straight lines from the centre or vertex covering 360 degrees at equal spacing and then making circles around the centre at varying diameters in simple progression. Yes, that's concentric circles with gradually 'increasing diameter difference'. The idea was to fill up the alternate trapezium like boxes thus formed with colour, each box being a 4 sided figure with two of the opposite arms being arcs and not straight lines. That looked too simple to me .. soon after. So I decided to vary (increase) the "difference in the change of diameter" of the concentric circles as we move outwards progressively. I hope this is clear. So a lot of trial and error happened and a lot of judgement happened about 'how much here' and 'how much then there' in order to contain everything and look substantial at the same time. So the difference in the diameter was then progressively increasing. That was my idea. And then to complicate things for myself, I decided to emanate curves from the centre rather than straight lines. Then I had to decide about the radius of these curves and the centres of these curves or arcs. Radii of these was decided, it's the same for each arc but of course each arc emanating from the centre has a different centre! It's symmetrical of course.
And Now, Concentric Circles with gradually decreasing diameter increase difference!
So I was actually going for a 'spiral big bang'. Really! Then Suddenly, ... and to make my life more difficult I decided to "decrease the increase in diameter" of the circles opening towards the outside in an ordered manner 'from somewhere'. That is why you see that the outside circles seem to get very close to each other as we move progressively outside, and that is the reason that the filled up arced trapezoidal boxes on the outside tend to decrease in width or thickness (whichever way you look at it) and collapse even though they are going outside, rather implying that they are moving on to the other side and implying that this is a sphere. "Movement of The Eye Everywhere"! :-)
Implosion As An AntiClimax
So this then becomes 'Spiral Big Bang Collapsing On The Outside'! The Explosion towards the outside gives way to an implosion as an anti climax on the other side. Wow!In fact if you move close to the monitor and then move away you may experience something moving. Even though it is a monitor, or even a phone, but you may notice the movement as you increase and decrease the distance of the screen from your eye while continuously looking at it.
Now this might be made geometrically easily on a computer, some might say, but I ask of you to attempt it even on a computer, and then very soon you will realise the head and the effort that has gone into it. This one has been manually done. And I had to be very accurate and steady. There is not one error. I mean never was an ink eraser used. You attempt this with Rotring or Staedtler Drafting Ink Pens in a Compass with an attachment, you will know.
This Graphic is not a very big giant, but it is a good size.
