Brief note: ‘Supermajor’ and what’s the illusion?

‘Supermajor’ is a piece currently showing as part of the ‘illusion’ exhibition in the Science Gallery in Dublin (

I was hoping to film it, and then write about it in relation to time. It is, however, broken. The guide I asked told me it will be fixed sometime next week. So….I’ll do it then.

In the meantime:

A. Here is what I plan to discuss when I do get to it:

1. What the illusion is. In brief, it is what is sometimes called the ‘Cartwheel Illusion’.

2. How it works.

3. What it tells us about the relationship between what we see and what is visually apparent to us.

4. Whether or not it is best to call it an illusion (where something seems to be there which is not) or, instead, a case of anosognosia (where something is there which seems not to be there).

5. How it relates to thinking about illusions of temporal order.

B. Here it is in a different gallery (yes, I could discuss it with this, but I want to wait until I can put it up on my own youtube channel):

    I Matt Kenyon, the artist who created Supermajor. I’ve been told that it is now up and running in science gallery if you wish to see it functioning in person. It was not working briefly because a valve issue with one of the pumps. Please let me know what you think of it.

      Hi Matt,

      Thank you very much for the interest in the post. I’m glad to see Supermajor is running again — I look forward to seeing it again in real life. I have seen it already there at the start, and it’s a fascinating piece of work, which is why I’m using it here. I’m happy to tell you what I think in writing the next post.

      I should say however that I’m using ‘Supermajor’ to make a particular point about what precisely is the ‘illusion’ in the effect in the work. In doing this, I focus only on the effect. But in doing this, I don’t intend to reduce the work to only that effect. I take it that it is only one aspect of the piece.
