Cardioid
More actions
A cardioid is a short linkage associated with an around. Historically a cardioid was considered to be a thumbaround cardioid, but in recent years the definition has expanded to all arounds. A cardioid takes one of two forms:
- Wiper -> Around
- Around -> Wiper
With the latter considered to be more difficult.
History
The name カージオイド (cardioid) was given by Hideaki in 1997, as it was one of the initial tricks in his website[1]. It was named that way since the trajectory of the pen tip resembles the cardioid shape (a heart). Although we can suppose that Kam knew about it, the trick doesn’t appear in Pentix nor Pentrix, nor on Phya’s 2004 trick list[2]. The earliest appearance of the name is in PenstudioZ, as a part of the breakdown of “1st Year Anniversary Celebration Final Strike” combo. [3]
The abstraction that a cardioid could also be done with other around's other than TA most probably comes from the Polish spinner Kanonier[4], in 2010. He did a pinkybak cardioid for the tournament MP ’10 and Smile, who was a judge, was impressed by it and named it Kanonier trick. Smile popularized it in French meetings: his friend Kinger used it in FPSB 5th and aaytowi2 was the first to do it twice. They tried to do its reverse, but Menowa* was able to pull it out first, during his WT15 run. The reverse Kanonier trick was presented to neir’da and i.suk as one of the hardest tricks. i.suk managed to master it and popularised it. Similar cardioid baks were discovered, most probably independently, by other JEB spinners: Beige, ctionist, Menowa*, and Yuera, among others[5].
Variations
Thumbaround Cardioid
The original cardioid variation, performed either on its own or continuously. Notated Wiper T1-T1 -> Thumbaround T1-T1. More recently Thumbaround T1-T1 -> Wiper T1-T1 is sometimes also considered to be a thumbaround cardioid. In the past this was once considered a unique trick.
Around Cardioid
When performed with arounds not associated with the thumb and caught in slots that do not use the thumb, Around -> Wiper is considered to be standard and substantially more difficult. This is because of the additional motion required to perform a catch at the correct position to perform a wiper.
Listed are some examples of around cardioids:
- Middlearound 23-23 -> Wiper 23-23 cont.
- PD Indexaround Reverse 12-12 -> PD Wiper 12-12
Fingerless Around Cardioid
A more difficult variation where the start position for the initial around is fingerless, usually from an aerial prior trick. When performed palm-down the difficulty increases significantly, due to the added requirement of providing air time while repositioning for a catch.
Listed are some examples of fingerless around cardioids:
- Index Spread 12-12 ~ FL Indexaround 12-12 -> Wiper 12-12
- PD FL Thumbaround 0.5 ~ FL PD Ringaround 23-23 -> PD Wiper Reverse 23-23
- PD FL Thumbaround Reverse 0.5 ~ FL PD Pinkyaround Reverse 34-34 -> PD Wiper Reverse 34-34
